  • Reproduction in Fungi: Genetical and Physiological Aspects by CHARLES G
    J. Genet., Vol. 73, Number 1, April 1994, pp. 55-56. (~) Printed in India. BOOK REVIEW Reproduction in Fungi: Genetical and Physiological Aspects By CHARLES G. ELLIOTT; Chapman & Hall, London, 1994; 310 pages; s 35.00 It is now ahnost one hundred years since Klebs (1986)laid the foundation of a scientific approach to the study of reproduction in fungi. Since then an extensive literature has accumulated on reproduction in fungi. To present this information ill terms of principles and concepts and to highlight the immediate problems for study is a daunting task. C. G. Elliott has made a commendable attempt in presenting an overview of the genetical and physiological aspects of fungal reproduction. Fungi are remarkable for producing many kinds of reproductive structures in many ways. They produce spores both asexually and sexually. A single fungus produces a single kind of sexual spore: oospores in phycomycetes, ascospores in ascmnycetes and basidiospores in basidiomycetes. The underlying genetical and physiological mechanisms in the formation of spores are complex and we are only beginning to discern them. The introductory chapter examines the advantages of both asexual and sexual reproduction and the persistence of sex in the face of the apparent advantage of asexual reproduction. The reader is reminded that sexual reproduction in fungi not only serves to generate variability, but also provides a means of repairing damaged DNA. Moreover, it can give rise to propagules resistant to unfavourable environmental conditions. In the chapters that follow, one learns that superimposed on the basic event of nuclear fusion are a variety of regulating medhanisms, the effects of which are to determine a successful mating.

  • THE Fungus FILES 31 REPRODUCTION & DEVELOPMENT
    Reproduction and Development SPORES AND SO MUCH MORE! At any given time, the air we breathe is filled with the spores of many different types of fungi. They form a large proportion of the “flecks” that are seen when direct sunlight shines into a room. They are also remarkably small; 1800 spores could fit lined up on a piece of thread 1 cm long. Fungi typically release extremely high numbers of spores at a time as most of them will not germinate due to landing on unfavourable habitats, being eaten by invertebrates, or simply crowded out by intense competition. A mid-sized gilled mushroom will release up to 20 billion spores over 4-6 days at a rate of 100 million spores per hour. One specimen of the common bracket fungus (Ganoderma applanatum) can produce 350 000 spores per second which means 30 billion spores a day and 4500 billion in one season. Giant puffballs can release a number of spores that number into the trillions. Spores are dispersed via wind, rain, water currents, insects, birds and animals and by people on clothing. Spores contain little or no food so it is essential they land on a viable food source. They can also remain dormant for up to 20 years waiting for an opportune moment to germinate. WHAT ABOUT LIGHT? Though fungi do not need light for food production, fruiting bodies generally grow toward a source of light. Light levels can affect the release of spores; some fungi release spores in the absence of light whereas others (such as the spore throwing Pilobolus) release during the presence of light.

  • Reproduction in Plants and Animals
    Reproduction in Plants and Animals Imagine a gardener checking on his growing plants at the beginning of spring. He notices a few tiny insects eating some of his plants. The gardener isn’t worried—a few insects are not a concern. But when he comes back several weeks later, his plants are covered in these small insects. There are at least ten times as many insects as there were several weeks ago! Where did all of these insects come from? How do organisms make more of their species? Reproduction produces offspring Reproduction is a process by which an organism produces offspring, or young. All organisms reproduce. If they didn’t, no species would survive past a single generation. The tiny insects developing Reproduction allows organisms to pass on their traits, or inside these eggs will grow characteristics to their offspring. Parents pass on their into adult insects. traits through their genetic material, or DNA. Sexual Reproduction requires two parents Sexual reproduction requires a male and female. Each parent contributes half of their genetic material, or DNA, to their offspring. The female contributes her DNA in an egg cell. The male contributes his DNA in a sperm cell. When the egg and sperm combine, they form the new offspring. Offspring may look similar to their parents, but they are not exact copies. In sexual reproduction, each offspring has a mixture of its parent’s traits. Parents may pass on dominant traits or recessive traits to their offspring. Each offspring may be different from its siblings. For These puppies are a product example, suppose the father in a human family does not of sexual reproduction have freckles, but his wife does.

  • Asexual Reproduction Only Involves One Parent Plant, and Does Not Need Sex Cells
    • Last week we covered pollination and fertilisation to create seeds. This is called sexual reproduction, but some plants can reproduce in other ways • Asexual reproduction only involves one parent plant, and does not need sex cells. This means they will not need to undergo pollination or produce seeds • New plants made through asexual reproduction are all exactly the same Asexual reproduction • Strawberries reproduce asexually • They send out runners over the ground • These runners sprout roots at various intervals and new plants grow • Once the plants are established, the runners die and rot away Asexual reproduction Parent plant New offspring Runners Asexual reproduction • Potatoes use tubers to reproduce • They send out underground stems that swell out at the end into tubers • These are young potatoes and contain stores of food (starch) • Each tuber can then grow into an entire new plant Asexual reproduction Parent plant Young tubers Stems growing underground Asexual reproduction • Instead of tubers, some plants produce bulbs instead • For example an onion will create bulbs towards the end of the season • These can be left in the ground to grow a new plant next year Asexual reproduction • Gardeners use asexual reproduction to create new plants that are identical to the parent plants • They cannot create new varieties this way • But they can produce required plants much quicker than growing them from seeds produced in sexual reproduction Asexual reproduction • The most common way for gardeners to create new plants asexually is by taking cuttings and growing them • These cuttings will develop their own roots and grow into an identical new plant What are the differences between sexual and asexual reproduction in plants? Do you know, or can you investigate, any other plants that reproduce in this way? Carry out your own investigation and keep a plant diary of what you find: - Try keeping an onion or a potato in the cupboard past its use by date.

  • Asexual and Sexual Reproduction Notes Unit 6
    Name ____________________________________________________________ Period _______ 7th Grade Science Asexual and Sexual Reproduction Notes Unit 6 Asexual Reproduction Type of reproduction in which a new organism is produced from ONE parent and the offspring is identical to the parent. Occurs in most plants, bacteria, protists, and low invertebrates. One parent Offspring are identical to the parents. Advantages and Disadvantages of Asexual Reproduction Advantages – Identical to parent, so will get all good characteristics. Disadvantages – Identical to parent, so will also get bad characteristics and is less able to adapt to environment. Types of Asexual Reproduction Regeneration – organism uses cell division to re-grow body parts. Example: starfish, salamander Vegetative Propagation – results in a new plant that is genetically identical to the parent plant (a clone). Examples: strawberry plant, vegetables, and crops. Budding – organism that produces a bud that breaks away to live on its own. Example: hydra Binary Fission – used by bacteria, an organism whose cells do not contain a nucleus copy then divide into two identical organisms Example: bacteria Sexual Reproduction Two parents Offspring are a combination of both parents and are therefore different from each parent. Advantages and Disadvantages of Asexual Reproduction Advantages – variety and/or diversity of offspring (color, shape, size, intelligence, ability, etc.), More able to adapt to environmental changes. Disadvantages – uniqueness, sometimes traits needed for survival are not passed on. Types of Sexual Reproduction Plants – when the reproductive cells of one plant fertilize (pollinate) the reproductive cells of another plant. This produces seeds that can grow into a new plant. Animals – when the reproductive cells of one animal fertilize the reproductive cells of another animal.

  • Plant Reproduction Asexual Reproduction
    Plant Reproduction Asexual Reproduction • Asexual reproduction is natural “cloning.” Parts of the plant, such as leaves or stems, produce roots and become an independent plant. Sexual Reproduction • Sexual reproduction requires fusion of male cells in the pollen grain with female cells in the ovule. Terms to know: • Haploid: having a single set of chromosomes in each cell. • Diploid: having two sets of chromosomes in each cell, one set from each parent. • Mitosis: cell division, which produces two genetically identical diploid cells. • Meiosis: reduction division, which produces four haploid reproductive cells. Terms to know: • Spore: haploid reproductive cell that leads to a gametophyte in plant alternation of generations. • Gamete: mature haploid male or female germ cell able to unite with another of the opposite sex in sexual reproduction to form a zygote. • Zygote: diploid, eukaryotic cell formed during fertilization event between two gametes, combining DNA of each gamete, containing the genetic information to form a new individual. Terms to know: • Sporophyte: diploid, multicellular stage which develops from zygote, produced when a haploid female cell is fertilized by a haploid male cell, produces haploid spores by meiosis. • Gametophyte: haploid, multicellular stage, develops from a spore by mitosis, produces haploid gametes by mitosis.
