Q

Fungi

A

-They are usually multicellular but some are single-celled (e.g. yeast)
-Multicellular fungi are mainly made up of thread-like structures known as hyphae that contain many nuclei and are organised into a network known as a mycelium
-Their cells contain a nucleus with a distinct membrane
-Their cells have cell walls made of chitin and do not contain chloroplasts
saprotrophic nutrition (decaying organic matter) and Some fungi are parasitic (feed on living material)
-They do not have nervous coordination

17
Q

Protoctists features

A
  • They are mainly microscopic and single-celled but some aggregate (group together) into larger forms
  • Their cells contain a nucleus with a distinct membrane
  • some have animal features and some have cell walls and chloroplast
    -They do not have nervous coordination
    Examples of protoctists include: amoeba, Paramecium, Plasmodium, Chlorella
18
Q

Prokaryotic features

A

always single-celled and do not contain a membrane bound nucleus.
