Fungi: An Overview of Their Major Phyla, Characteristics, and Role in Nature, Quizzes of Biology

Definitions and information about various aspects of fungi, including their major phyla (chytridiomycota, zygomycota, ascomycota, and basidiomycota), their nutritional mode (heterotrophic), their cellular structure (cell wall made of chitin, presence of hyphae and mycelium), and their reproductive modes (asexual and sexual). It also discusses unique features of fungal sexual reproduction and the roles of fungi in nature, such as their contributions to medicine, plant growth, and decomposition.

aseptate (coenocytic) 2. zygosporangia 3. some are parasites

of animals

TERM 18

Zygosporangia

DEFINITION 18

Specialized sexual reproductive structure
