midterm review: fungi Flashcards

Q
What molecular and structural evidence supports the hypothesis that fungi are more closely related to animals than to plants?
A
- Fungi and animals belong to the supergroup Opisthokonta.
- They both contain chitin in their cell structure and use glycogen to store energy
- fungi do not photosynthesize. Instead, they absorb nutrients from their environment, similar to animals that consume organic matter.
- Fungi have flagella similar to animal sperm.

Q
Explain why fungi are placed in the Opisthokonta clade. What characteristics do they share with animals, and how do they differ?
A
- Fungi are placed in the opisthokonta clade because they share a common ancestor with animals and choanoflagellates.
- Fungi have chitin based cell walls, animals don’t have cell walls
- fungi are absorptive heterotrophs, animals are ingestive heterotrophs
- fungi are non motile, animals are motile
- fungis body structure consists of hyphae and mycelium while animals are composed of tissues and organs
