Q

What are the common features of living organisms in the fungi kingdom?

A

Single or multicellular organisms
Yeast is an example of a single cell
Multicellular are made up of fine threads known as hyphae - each hyphae contains many nuclei
Do not contain chlorophyll so secrete digestive enzymes outside the cells onto animal or plant material- this is saprotrophic nutrition
Some fungi are pathogens and cause diseases in other organisms e.g. Ringworm
