Fruits: Kinds and Terms
FRUITS: KINDS AND TERMS THE IMPORTANT PART OF THE LIFE CYCLE OFTEN IGNORED Technically, fruits are the mature ovaries of plants that contain ripe seeds ready for dispersal • Of the many kinds of fruits, there are three basic categories: • Dehiscent fruits that split open to shed their seeds, • Indehiscent dry fruits that retain their seeds and are often dispersed as though they were the seed, and • Indehiscent fleshy fruits that turn color and entice animals to eat them, meanwhile allowing the undigested seeds to pass from the animal’s gut We’ll start with dehiscent fruits. The most basic kind, the follicle, contains a single chamber and opens by one lengthwise slit. The columbine seed pods, three per flower, are follicles A mature columbine follicle Milkweed seed pods are also large follicles. Here the follicle hasn’t yet opened. Here is the milkweed follicle opened The legume is a similar seed pod except it opens by two longitudinal slits, one on either side of the fruit. Here you see seeds displayed from a typical legume. Legumes are only found in the pea family Fabaceae. On this fairy duster legume, you can see the two borders that will later split open. Redbud legumes are colorful before they dry and open Lupine legumes twist as they open, projecting the seeds away from the parent The bur clover modifies its legumes by coiling them and providing them with hooked barbs, only opening later as they dry out. The rattlepods or astragaluses modify their legumes by inflating them for wind dispersal, later opening to shed their seeds. -

Plant Anatomy Lab 13 – Seeds and Fruits
Plant Anatomy Lab 13 – Seeds and Fruits In this (final) lab, you will be observing the structure of seeds of gymnosperms and angiosperms and the fruits of angiosperms. Much of the work will be done with a dissecting microscope, but a few prepared slides will also be used. A set of photocopied images from the plant anatomy atlas will be available as a handout. You can use the handout to help you identify the various structures we will be looking at in seeds and fruits. Also, a fruit key is available as a separate handout. Remember that we will be considering only a small fraction of the structural diversity present among seeds of gymnosperms and the seeds and fruits of angiosperms. Seeds Gymnosperms Obtain a prepared slide of an immature pine ovule and of a mature pine ovule. You will be able to tell them apart from the following observations. • Looking at the immature ovule, you will see a megagametophyte with one or more archegonia at the end near the micropyle. The egg inside may or may not have been fertilized. • Also find the nucellus and integument tissues. Next look at a slide of a mature ovule. Instead of the megagametophyte, you will find a developing embryo. As part of this embryo, find the • cotyledons, • the radicle (embryonic root), and the • shoot apical meristem. Depending on its age, you may also notice procambial strands running between the embryonic root and the shoot apex. Points to consider: We might say that gymnosperms and angiosperms have seeds but only angiosperms have fruits - Why is that? Why don’t we consider the seed cone of a pine tree a fruit? Angiosperms Dicot Obtain a bean pod. -

Describing the Fruits Group Activity
Describing The Fruits Group activity: Each member of the group must select 5 cards and describe each of them, focusing the card on the camera of the mobile device with the application Aprender Es Divertido and the other members of the group must guess what fruit it is. If after 2 minutes the other members have not said the name of the fruit, the person who is describing it must do an activity proposed by the other members. It is a drupaceous fruit of a small tree (Prunus dulcis synonym P. amygdalus) of the rose family with flowers and young fruit resembling those of the peach; especially : its ellipsoidal edible kernel used as a nut It is the fleshy, usually rounded red, yellow, or green edible pome fruit of a usually cultivated tree (genus Malus) of the rose family. It is an oval orange-colored fruit of a temperate-zone tree (Prunus armeniaca) resembling the related peach and plum in flavor It is an elongated usually tapering tropical fruit with soft pulpy flesh enclosed in a soft usually yellow rind It is a usually black or dark purple juicy but seedy edible aggregate fruit of various brambles (genus Rubus) of the rose family It is an edible blue or blackish berry of any of several North American plants (genus Vaccinium) of the heath family it is a red, or blackish juicy drupe of the rose family. it is the edible nut of any of a genus (Castanea) of trees or shrubs of the beech family. It is the drupaceous fruit coming ffrom a palm whose outer fibrous husk yields coir and whose nut contains thick edible meat and, in the fresh fruit, a clear liquid It is the brown, oblong edible fruit of a palm (Phoenix dactylifera). -

INTRODUCTION Crop plants are our greatest heritage from prehistory (Harlan 1992; Diamond 2002). How, where, and when the domestication of crops plants occurred is slowly becoming revealed although not completely understood (Camp et al. 1957; Smartt and Simmonds 1995; Gepts 2003). In some cases, the genetic distance between wild and domestic plants is so great, maize and crucifers, for example, that their origins are obscure. The origins of the ancient grains (wheat, maize, rice, and sorghum) and pulses (sesame and lentil) domesticated in Neolithic times have been the subject of intense interest and the puzzle is being solved with the new evidence based on molecular biology (Gepts 2003). -
Sorbus Torminalis Present of Vascular Plants Isles (1992)
Article Type: Biological Flora BIOLOGICAL FLORA OF THE BRITISH ISLES* No. 286 List Vasc. Pl. Br. Isles (1992) no. 75, 28, 24 Biological Flora of the British Isles: Sorbus torminalis Peter A. Thomas† School of Life Sciences, Keele University, Staffordshire ST5 5BG, UK Running head: Sorbus torminalis Article †Correspondence author. Email: [email protected] * Nomenclature of vascular plants follows Stace (2010) and, for non-British species, Flora Europaea. Summary 1. This account presents information on all aspects of the biology of Sorbus torminalis (L.) Crantz (Wild Service-tree) that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of the Biological Flora of the British Isles: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral and seed characters, herbivores and disease, history, and conservation. 2. Sorbus torminalis is an uncommon, mostly small tree (but can reach 33 m) native to lowland England and Wales, and temperate and Mediterranean regions of mainland Europe. It is the most shade-tolerant member of the genus in the British Isles and as a result it is more closely associated with woodland than any other British species. Like other British Sorbus species, however, it grows best where competition for space and sunlight is limited. Seedlings are shade tolerant but adults are only moderately so. This, combined with its low competitive ability, restricts the best growth to open areas. In shade, saplings and young adults form a sapling bank, This article has been accepted for publication and undergone full peer review but has not Accepted been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record. -

Illustrated Glossary of Botanical Terms
ILLUSTRATED GLOSSARY OF BOTANICAL TERMS FLORA OF THE CHICAGO REGION A Floristic and Ecological Synthesis (Wilhelm & Rericha, 2017) Published by the Indiana Academy of Science (IAS) September 20, 2020 The glossary for the 4th edition of Plants of the Chicago Region (Swink & Wilhelm, 1994) had nearly 200 individual drawings on 12 intercalated plates. These illustrations were popular and a useful feature. However, as the page count in the follow-up book, Flora of the Chicago Region (FCR), needed to be reduced, the decision was made not to include an illustrated glossary. In an attempt to make FCR a more useful educational tool, it was recently decided to publish an adjunct illustrated glossary and to post it on the website maintained by the Conservation Research Institute (CRI). The new glossary has been expanded substantially, providing double the number of individual illustrations and terms. The glossary is available for use without charge. We merely ask that all use of these illustrations and associated glossary be limited to educational and non-commercial activities, and that the IAS, FCR and CRI each be credited in all use. THE ARTISTS: Paul Nelson penned the drawings used in the 4th edition of PCR. Mary Marguerite Lowther created the line art used for each genus in FCR. Kathleen Marie Garness produced the illustrations used for the addended FCR glossary. We applaud their talent. EDITOR’S NOTE: The senior author is a master key writer—the best I know. His keys are clean and precise. Anyone truly interested in learning plants (i.e., distinguishing species) will encounter and at some point will need to know how to use a dichotomous key, which will require a familiarity with botanical terminology. -
Why Blackberries and Apples Are Not Berries
Why Blackberries and Apples Are Not Berries Of the strawberry, blackberry and raspberry, only the latter comes close to being a berry. The first two aren't even fleshy fruits; the tomato, which many still regard as a vegetable, is a pure berry, and lemons are modified berries. Here’s why. There are five types of fleshy fruits. (1) In the pome, which as the name suggests includes the apple, pear and less popular hawthorn, the receptacle or floral tube becomes the edible part, and it surrounds the ex- ovary, that shell around the seeds. (2) In the drupe (peaches, plums, cherries) we're eating the outer wall of the ovary. The inner wall is stony (the pit) and it contains the seed, usually laced with a cyanide -related compound. (3) In the pure berry, the entire ovary becomes fleshy, and it can have one to many seeds. Examples include grapes, tomatoes, eggplants, kiwis and persimmons (starry cross-section is pictured). The raspberry is an aggregate of berries because it’s a fusion of many ovaries. (4) The pepo, an accessory berry, has its receptacle and ovary wall fusing to make the hard rind. We're basically eating the rest of the ex-ovary. Examples include cantaloupes, cucumbers and squash. (5) Citrus fruits such as lemon and oranges are hesperidia or modified berries because the ovary wall becomes the rind, and again we're eating the rest of what was the ovary. The strawberry is not a berry, nor is most of it a fleshy fruit. The fleshy, edible part comes from the receptacle of the flower, and the botanical fruits are miniature and surround the seeds. -
