The shoot system is above ground and includes the organs such as leaves, buds, stems, flowers (if the plant has any), and fruits (if the plant has any). CLICK HERE TO RETURN TO THE TABLE OF CONTENTS 3 Plant Stems Plant stems provide support for the plant and allow nutrients and water to travel throughout the plant. CLICK HERE TO RETURN TO THE TABLE OF CONTENTS 4 Leaves The leaves are the sites of food production for the flowering plant. It is here that the plant acquires light energy and carbon dioxide for photosynthesis and releases oxygen into the air. CLICK HERE TO RETURN TO THE TABLE OF CONTENTS 5 Leaves Leaves can have various shapes and forms, but they all basically consist of a blade, veins, and a petiole. The blade is the flat extended part of the leaf. The veins run throughout the blade and provide a transport system for water and nutrients. The petiole is a short stalk that attaches the leaf to the stem. CLICK HERE TO RETURN TO THE TABLE OF CONTENTS 6 Flower The flower is responsible for seed development and reproduction. There are four main flower parts in angiosperms: sepals, petals, stamens, and carpels.

CLICK HERE TO RETURN TO THE TABLE OF CONTENTS 9 Stamen The stamen which consists of a filament and an anther is considered the male portion of a plant. It is the part of the flower that produces pollen. CLICK HERE TO RETURN TO THE TABLE OF CONTENTS 10 The Carpel The carpel is considered the female portion of the plant. The carpel consists of the stigma, style, and ovary. Stigma - the tip of the carpel that is sticky in order to collect pollen. Style - the slender, neck-like portion of the carpel that leads to the ovary. Ovary - structure at the base of the carpel that houses the ovule or egg.

Flowers and Maturation 3Rd - 5Th Grade
Flowers and Maturation 3rd - 5th Grade Introduction Over 90% of all plants are angiosperms or flowering plants. When you think of flowers, you probably think of a rose, carnation or maybe, a tulip . It is not just flowers that are flowering plants. In the spring and summer, you can find flowers in many places but, many plants have flowers that you never see. The grass in the yard is a flowering plant but, you have probably never seen their flower. They are hidden inside the plant. A plant lives to produce more plants and it needs a flower to do that. Flowers are responsible for producing seeds This lesson will teach you the parts of a flower and how those parts work. Objectives • Students will understand the role of flowers in the life of a plant. • Students will understand the basic parts of a flower. • Students will understand the function of the parts of the flower. • Students will understand seed development. Background First, let us look at the diagram of a flower. Photo provided by: https://www.colourbox.com/vector/a-common-flower-parts-vector-34289070 kansascornstem.com A “perfect flower” has both male and female parts. There are also parts that are not male or female. The sepal are leaves that protect the flower as it grows. They peel back as the flower grows. The petals give many flowers their beauty, but the most important job they have are to attract insects that will help them in the process of producing seeds. You will read more about that later.

Plant Terminology
PLANT TERMINOLOGY Plant terminology for the identification of plants is a necessary evil in order to be more exact, to cut down on lengthy descriptions, and of course to use the more professional texts. I have tried to keep the terminology in the database fairly simple but there is no choice in using many descriptive terms. The following slides deal with the most commonly used terms (more specialized terms are given in family descriptions where needed). Professional texts vary from fairly friendly to down-right difficult in their use of terminology. Do not be dismayed if a plant or plant part does not seem to fit any given term, or that some terms seem to be vague or have more than one definition – that’s life. In addition this subject has deep historical roots and plant terminology has evolved with the science although some authors have not. There are many texts that define and illustrate plant terminology – I use Plant Identification Terminology, An illustrated Glossary by Harris and Harris (see CREDITS) and others. Most plant books have at least some terms defined. To really begin to appreciate the diversity of plants, a good text on plant systematics or Classification is a necessity. PLANT TERMS - Typical Plant - Introduction [V. Max Brown] Plant Shoot System of Plant – stem, leaves and flowers. This is the photosynthetic part of the plant using CO2 (from the air) and light to produce food which is used by the plant and stored in the Root System. The shoot system is also the reproductive part of the plant forming flowers (highly modified leaves); however some plants also have forms of asexual reproduction The stem is composed of Nodes (points of origin for leaves and branches) and Internodes Root System of Plant – supports the plant, stores food and uptakes water and minerals used in the shoot System PLANT TERMS - Typical Perfect Flower [V.

Using RNA-Seq to Characterize Pollen–Stigma Interactions for Pollination
www.nature.com/scientificreports OPEN Using RNA‑seq to characterize pollen–stigma interactions for pollination studies Juan Lobaton1,3*, Rose Andrew1, Jorge Duitama2, Lindsey Kirkland1, Sarina Macfadyen3 & Romina Rader1 Insects are essential for the reproduction of pollinator‑dependent crops and contribute to the pollination of 87% of wild plants and 75% of the world’s food crops. Understanding pollen fow dynamics between plants and pollinators is thus essential to manage and conserve wild plants and ensure yields are maximized in food crops. However, the determination of pollen transfer in the feld is complex and laborious. We developed a feld experiment in a pollinator‑dependent crop and used high throughput RNA sequencing (RNA‑seq) to quantify pollen fow by measuring changes in gene expression between pollination treatments across diferent apple (Malus domestica Borkh.) cultivars. We tested three potential molecular indicators of successful pollination and validated these results with feld data by observing single and multiple visits by honey bees (Apis mellifera) to apple fowers and measured fruit set in a commercial apple orchard. The frst indicator of successful outcrossing was revealed via diferential gene expression in the cross‑pollination treatments after 6 h. The second indicator of successful outcrossing was revealed by the expression of specifc genes related to pollen tube formation and defense response at three diferent time intervals in the stigma and the style following cross‑pollination (i.e. after 6, 24, and 48 h). Finally, genotyping variants specifc to donor pollen could be detected in cross‑pollination treatments, providing a third indicator of successful outcrossing. Field data indicated that one or fve fower visits by honey bees were insufcient and at least 10 honey bee fower visits were required to achieve a 25% probability of fruit set under orchard conditions.

Half the patients felt stigmatised, higher proportions being observed among younger patients and among those with a colostomy. Feelings of stigma were associated with poor health, particularly emotional disorders, with the presence of other medical problems, and with disablement. Patients who perceived stigma made more use of were medical services but less satisfied with them, particularly with regard to communication with by guest. Protected copyright. health professionals. Socio-economic factors, such as employment status, higher income, and higher social and housing class, did not protect patients against feeling stigmatised by cancer or by colostomy. Most patients, with or without stigma, enjoyed close relationships with intimates, but the stigmatised were more likely to have withdrawn from participation in social activities. Assessing stigma by self-rating gives information which adds to that obtained by the usual methods of assessing quality of life. Treatment for rectal cancer involves the majority of proof-bags, there are still problems with odour, noise, patients in radical mutilating surgery, the burden of a and leakage.24 Moreover, the practicalities of colostomy, and low expectation of survival."q managing a stoma physically violate strong social Although new techniques to reduce the number of taboos about defaecation.

Plant Reproduction | Topic Notes
Plant Reproduction | Topic Notes Sexual reproduction is the fusion of male and female gametes to produce a diploid zygote. (The new individual is genetically different from both parents). Advantages include genetic variation, reduced competition (between parent & offspring) and good chance of surviving harsh winter. A disadvantage is that there’s a long period of growth required. Structure of flowering plant: Megaspore (egg) formation & microspore (pollen) formation: The carpel (female part of the flower) is composed of the stigma (sticky to trap pollen grains), style (supports stigma in best position to trap pollen grains) and ovary (contains 1 or more ovules which following fertilisation will develop into seeds). The stamen (male part of the flower) is composed of the anther (produces pollen grains) and filament (supports anther in best position to transport pollen grains). Sepals support the developing flower before it blooms. Petals may be bright coloured in insect pollinated plants (to attract them). The receptacle is the organ from which the flower develops and functions in supporting it. Pollination is the transfer of pollen from the anther to the stigma of a flower of the same species. It may be: 1. Self-pollination: the transfer of pollen from the anther to the stigma in the same plant. 2. Cross-pollination: the transfer of pollen from the anther to the stigma of a different plant but of the same species. 1 Plant Reproduction | Topic Notes Fertilisation is the union of a haploid male gamete with a haploid female gamete, to produce a diploid zygote. Once a pollen grain has landed on the stigma, the tube nucleus moves down through the stigma and style forming a pollen tube and enters the ovule at the micropyle, guided towards the egg by chemotropism, the tube nucleus then degenerates.

The shoot system is composed of the stem and its lateral appendages: leaves, buds, and flowers. Leaves are arranged in different patterns (phyllotaxis): alternate, opposite, whorled, and spiral. 2. Stems provide support to the leaves, buds, and flowers. They conduct water and nutrients and produce new cells in meristems (shoot apical meristem, primary and secondary meristems). 3. Dicot stems and monocot stems are usually different. Dicot stems tend to have vascular bundles distributed in a ring, whereas in monocot stems they tend to be scattered. 4. Stems are composed of the following: epidermis, cortex and pith, xylem and phloem, and periderm. 5. Secondary xylem is formed by the division of cells in the vascular cambium and is called wood. The bark is composed of all of the tissues outside the vascular cambium, including the periderm (formed from cork cambium) and the secondary phloem.

When the insect gets hungry again, it gets attracted to another flower’s bright colours and fragrant scent. As the insect is gathering the nectar it rubs against the anthers which rub pollen onto the insect. The ovary of the flower turns into seeds which will then be dispersed so that new plants will be able to grow somewhere else. Part of this pollen travels down the style and then into the ovary. The insect arrives on the flower to collect nectar. This is a sweet liquid which makes perfect insect food.

All rights reserved. 1058-5893/2008/16906-0002$15.00 DOI: 10.1086/533602 FLORAL STRUCTURE AND DYNAMICS OF NECTAR PRODUCTION IN ECHINACEA PALLIDA VAR. ANGUSTIFOLIA (ASTERACEAE) Tyler J. Wist and Arthur R. Davis1 Department of Biology, University of Saskatchewan, 112 Science Place, Saskatoon, Saskatchewan S7N 5E2, Canada The reproductive structure of the disk florets of Echinacea pallida var. angustifolia (Asteraceae) in relation to insect pollination was investigated using light, fluorescence, and scanning electron microscopy. The study of this self-incompatible species emphasized pollen production, pollen-stigma interactions, transmitting tissue, and vasculature within the style. Nectary structure and nectar production dynamics were also examined. Produced in the fused anther tubes, the trinucleate pollen with yellow pollenkitt was plentiful per floret, yielding a pollen : ovule ratio of 24,130. Encircling the style base at the ovary summit, the floral nectary pos- sessed modified stomata whose pores, as well as nonstomatal gaps in the epidermis, provided apoplastic pathways for nectar escape and reabsorption. Phloem alone supplied the gland interior, the sieve element– companion cell complexes reaching up to the nectary epidermis. Nectar was hexose dominant, its volume and nectar-sugar quantity per floret peaking on the afternoon of the first day of anthesis until the morning of the second day. Nectar production only occurred in half of the florets for 3 d, rarely for 5 d. Potential honey production from fields of this species was estimated at 2.1–11.9 kg/ha. Keywords: floral nectar, nectary, pollen-stigma interactions, pollination, style.

Morphology and Vascular Anatomy of the Flower of Angophora Intermedia
© Landesmuseum für Kärnten; download www.landesmuseum.ktn.gv.at/wulfenia; www.biologiezentrum.at Wulfenia 13 (2006): 11–19 Mitteilungen des Kärntner Botanikzentrums Klagenfurt Morphology and vascular anatomy of the ﬂ ower of Angophora intermedia DC. (Myrtaceae) with special emphasis on the innervation of the ﬂ oral axis Sergey A. Volgin & Anastasiya Stepanova Summary: A peculiar receptacle structure in Angophora intermedia DC. (Myrtaceae) has been determined by a vascular-anatomical method. The vascular system of the fl ower of A. intermedia consists of numerous ascending bundles and girdling bundles in the hypanthium and the inferior ovary wall. In the central column of the trilocular ovary we found a dense conical plexus of vascular bundles supplying the placentae (infralocular plexus). It is connected with ascending bundles of the receptacle in the ovary base. In its central part it contains “hanged” bundles and blind bundles, so it seems to be a residual stele of a rudimentary fl oral apex. Thus, the receptacle ofA. intermedia is toroidal at the level of fl oral organs and conical above the carpel node. Keywords: Angophora intermedia, Myrtaceae, fl ower morphology, vascular system, fl oral axis, innervation, anatomy The fl oral development in different species of Myrtaceae has been studied precisely to elucidate the homology of the inferior ovary, hypanthium, operculate perianth and stamens of the polymerous androecium (PAYER 1857; MAYR 1969; BUNNIGER 1972; DRINNAN & LADIGES 1988; RONSE DECRAENE & SMETS 1991; ORLOVICH et al. 1996). Developmental and histogenetical studies have shown, that the receptacle in the fl ower of Myrtaceae is cup-like and take part to certain extent in the formation of the inferior ovary wall and the hypanthium (PAYER 1857; BUNNIGER 1972; RONSE DECRAENE & SMETS 1991).
