Eukaryote: Fungi

1. Eukaryote: Fungi Structural components Characteristics

3. Structures • Fungi are diverse& widespread • Are essential for the well- • being of most terrestrial • ecosystems because they • break down organic material • and recycle vital nutrients scale cap gill spore ring stalk vulva fruit body (reproductive part that generates spores) hyphae mycelia (absorb nutrients from the soil)

4. Types of Fungal Nutrition Fungi are heterotrophs (consumers):  Fungi secrete exoenzymesthat break down complex molecules and then they absorb the remaining smaller compounds as nutrients

9. Replication 1. Hyphae from two different mating types fuse to form a zygospore 2. A thick wall develops around the zygospore which allows it to survive long periods of dormancy 1. Spores are produced in the sporangium and released into the environment 3. In optimal conditions, the spore germinates and a sporangium start growing Asexual Sexual

10. Pathogens About 30% of known fungal species are parasites, mostly on or in plants (a) Corn smut on corn (b) Tar spot fungus on maple leaves (c) Ergots on rye
