Mycorrhizae are - Study guides, Class notes & Summaries

1. In most fungi, karyogamy does not immediately follow plasmogamy, which consequently A) means that sexual reproduction cannot occur. B) decreases the overall size of the organism. C) allows fungi withstand harsh conditions in a dormant state. D) results in heterokaryotic or dikaryotic cells. - Answer-D) results in heterokaryotic or dikaryotic cells. 2. Which of the following best describes the physical relationship of the partners involved in lichens? A) Fungal cells are enclosed within ...

Monocot root system - Answer-Fibrous Eudicot root system - Answer-Taproot Mycorrhizae - Answer-Symbiotic relationship between plants and fungi (hyphae) - increase in surface area Nodes - Answer-Portion(s) of the stem where leaves attach Internodes - Answer-Segments of the stem where no leaves attach Terminal buds - Answer-Composed of developing leaves and are partly responsible for inhibiting the growth of axillary buds by apical dominance. Apical dominance - Answer-Plants grow verticall...

3 mechanisms for prokaryot genetic recombination - 1.)Transformation 2.)Conjugation 3.)Transduction Absolute dating - -Radioactive isotopes decay over regular annual time periods (half-lives) -C14 5,700 yrs - radioactive isotopes vs stable isotopes -stable isotopes stay the same after the organism dies Alexander Fleming - -Discovered Penicillin -microbe v. microbe interaction -Capitalized on mistake in the lab, left plate out and fungus grew on it Algae - -Protist -plant like; photoau...

WSU Biology 106 Exam 2 >> Questions and Answers Graded A++ Fungi heterotrophs that feed by absorption Heterotrophs absorb nutrients from outside the body Roles of fungi decomposers, parasites, mutualists (symbiotic and microrizzae), early land colonizers What do fungi use to break complex molecules? Enzymes Chitin made of cellulose, make up the cell walls of fungi Hyphae continuous strands above/below ground, generate spores, colonizes soil Fungi life cycle Mycellum a ...

How do fungi use absorptive heterotrophy? Correct Answer-Fungi secrete hydrolytic enzymes into their surrounds that break down complex molecules to smaller organic compounds that the fungi can absorb into their bodies and use. Other types of fungi use enzymes to penetrate the walls of cells, enabling the fungi to absorb nutrients from the cells. What are hyphae? Correct Answer-Multicellular fungi typically form a network of tiny filaments called hyphae. Hyphae consist of tubular cell walls su...

Mycorrhizae : Symbiotic organisms (aka symbionts) with plants that live on their roots, helping the plant gain nutrients Nerve net : A nervous system that moves neural signals in all directions from the stimuli, found in invertebrates like hydra Malpighian tubules : Tubes in an insect that help with osmoregulation and excretion; they move waste into the main gut for removal. "Kidneys" of arthropods, they absorb ammonium and convert it into uric acid, then into the main gut for rem...

Brooks Biodiversity Unit 2 Exam Study Guide 2024 with complete solution. The Primary role of Fungi Decomposers- they break things down Modes of Nutrition in Fungi Heterotrophs with extracellular digestion Exoenzymes Fungi Release these enzymes outside of the cell wall. Break down complex molecules into smaller organic molecules which can be absorbed. Extracellular Digestion The release of exoenzymes out side of the cell wall, followed by the absorption of nutrients.. Saprobes Fungi...

Although fungi generally lack extensive cellular specialization, what feature of hyphal growth makes them so well suited as decomposers, mutualistic symbionts, and pathogens? correct answer: a large surface area Fungi have unique life cycles. A fungus that has two parental nuclei in one cell is referred to as a ___________. correct answer: dikaryon dikaryon correct answer: hyphae with cells having 2 different nuclei in each cell. Chytrids are thought to be the ancestral group of fung...

Kingdom Fungi - decomposers, contain no chlorophyll (non photosynthetic, majority are multicellular, some unicellular, non-motile, cell walls contained chitin, and reproduce sexually and asexually multicellular fungi - molds and mushrooms unicellular fungi - yeast asexual reproduction - reproduction through spores sexual reproduction - reproduction through mating of hyphae filaments Mycelium - distinctive body; composed of microscopic, branched filaments known as hyphae. Involved ...
