Q

Fungus like protists

A

Slime molds or water molds
Similiar to kingdom fungi, fungi like protists reproduce via spores
No chitin

Q

Animal like protists (protozoa)

A

Based on motility; cilia or flagella
Capable of movement
single celled

Q

Filamentous fungi

A

Multicellular (molds/ mushrooms)
Sexual or asexual repdocution
mushroom grow outward from mycelium

17
Q

Mycelium

A

Network of fungi filaments (hyphae) that connect fungi together

18
Q

Mycelium functions

A

Secrete enzymes that break down organic matter
Releases nutrients for absorption by hyphae
Allows fungi to be effective decomposers

19
Q

Hyphae

A

Filamentous branches produced by multicellular fungi as they grow

20
Q

Septate hyphae

A

Have septa (cells walls that seperate hyphae)

21
Q

Coenocytic hyphae

A

No division of hyphae
Multinucleated

22
Q

Reproduction

A

Can reproduce sexually, asexually, or both
Haploid for most of their life cycle
