Question
Ch 31 Objectives . List the characteristics that distinguish fungi from members of other kingdoms 2. Explain how fungi acquire their nutrients. . Describe the basic body plan of a fungus. 4. Distinguish between ectomycorrhizal fungi and arbuscular s. Describe the processes of plasmogamy and karyogamy in 6. Describe the heterokaryotic/dikaryotic stages in fungal life 7. Describe the evidence that suggests that Fungi and mycorrhizal fungi fungi cycles Animalia are sister kingdoms. What is the evidence that the common ancestor for both was a "protists"? 8. Explain why Ectomycorrhizal and Abuscular mycorrhizal 9. What do fungi and plants give each other in their o. Be able to distinguish between the sexual structure that fungi (Glomeromycota) are ecologically important. relationship? characterizes each group: zygomycetes (e.g. Rhizopus), ascomycetes (e.g. Aspergillus, Penicillium), and basidiomycetes (e.g. white cap mushroom) . Describe the structure of a lichen. Explain the roles of the fungal and photosynthetic partners of the lichen.Explanation / Answer
1. Fungi not contain chlorophyll, so phhotosynthesis not occur like plants.
Fungi reprouce by spores
Cell wall made up of chitin.
2. fungi grow off dead plants or animals to obtain nutrients
3. 1. Cell wall, 2. hyphae 3. fruiting body
4. ectomycorrhizal fungi - fungus penetrates the cortical cells of the roots of a vascular plant.
help plants to capture nutrients such as phosphorus and micronutrients from the soil.
arbuscular mycorrhizal
hyphal sheath, or mantle, covering the root tip and a hartig net of hyphae surrounding the plant cells within the root cortex.
5. Plasmogamy - cell membranes and cytoplasm of these haploid cells then fuse together. Single cell with two nuclei.
Karyogamy - The pronuclei then fuse together
6. dikaryotic fungi contains only 2 genetically different nuclei
heterokaryotic fungi may contains more than 2 nuclei
7. Fungi ansd animalia are both are eukaryotes contains
80S ribosome.Linear chromosome, Methione
9. Symbiosis
10. zygomycetes - Hyphae are usually nonseptate, Asexual spores; mostly sporangiospores
ascomycetes - Sexual spores; most produce ascospores in asci.Hyphae with porous septa.
basidomycetes - Sexual reproduction by means of basidia and basidiospores, Asexual sprores: conidia
Incompletely septate hyphae
