Plants structure

Multicellular

Contain chloroplasts —> carry out photosynthesis

Cell walls made from cellulose

Permanent vacuole

Fungi structure

Multicellular and unicellular

Cell walls of chitin

No chloroplasts —> cannot photoynthesise

Organised in mycelium with thread-like hyphae

Saprothrophic nutrition

Animals

Multicellular

Cannot photosynthesise

Nervous systems to coordinate movement

Protocists

Single celled organisms

Protocist examples

Amoeba

Chlorella

Virus examples

Tobacco mosaic virus

HIV/AIDS

Saprotrophic nutrition

Fungi Feed by extracellular secretion of enzymes onto food material and absorption of the organic material

Why are viruses not classified as living organisms

MRSGREN

-can only reproduce in living cells

HIV/AIDS

Weakens the immunes system
