1. Answer:

Characteristics of Fungi

1. Fungi are eukaryotic, non-vascular, non-motile and heterotrophic organisms.
2. They MAY be unicellular or filamentous.
3. They reproduce by means of spores.
4. Fungi exhibit the phenomenon of alternation of generation.
5. Fungi lack chlorophyll and hence cannot perform photosynthesis.
6. Fungi store their food in the form of starch.
7. Biosynthesis of chitin occurs in fungi.
8. The nuclei of the fungi are very small.
9. During mitosis, the NUCLEAR envelope is not dissolved.
10. The fungi have no embryonic stage. They develop from the spores.
11. The mode of reproduction is sexual or asexual.
12. Some fungi are parasitic and can infect the host.
13. Fungi produce a chemical called pheromone which leads to sexual reproduction in fungi.
14. For eg., MUSHROOMS, moulds, yeast.

Based on Mode of nutrition

• Saprophytic – The fungi obtain their nutrition by feeding on dead organic substances. Examples: Rhizopus, Penicillium, and Aspergillus.
• Parasitic – The fungi obtain their nutrition by living on other living organisms (Plants or animals) and absorb nutrients from their host. Examples: Taphrina, and Puccinia.
• Symbiotic – These fungi LIVE by having an interdependent relationship association with other species in which both are mutually benefited.Examples: Lichens and mycorrhiza. Lichens are the symbiotic association between algae and fungi. Here both algae and fungi are mutually benefited as fungi provide shelter for algae and in reverse algae synthesis carbohydrates for fungi.

Based on Spore Form

• Zygomycetes – These are formed by the fusion of two different cells. The sexual spores are known as zygospores while the asexual spores are known as sporangiospores. The hyphae are without the septa.
• Ascomycetes – They are also called as sac fungi. They can be coprophilous, decomposers, parasitic or saprophytic. The sexual spores are called ascospores. Asexual reproduction occurs by conidiospores. EXAMPLE – Saccharomyces
• Basidiomycetes – Mushrooms are the most commonly found basidiomycetes and mostly live as parasites. Sexual reproduction occurs by basidiospores. Asexual reproduction occurs by conidia, budding or fragmentation. Example- Agaricus
• Deuteromycetes – They are otherwise called imperfect fungi as they do not follow the regular reproduction cycle as the other fungi. They do not reproduce sexually. Asexual reproduction occurs by conidia. Example – Trichoderma.
