Chemical structure of cellular walls of mold fungi is similar to:

a) Plants

b) Lobsters

c) Armadillos

b) Lobsters, because the shell of arthropods (crustations, insects, spiders, and such animals) and the cell walls of fungi (molds) are made of chitin, a structural polysaccharide (sugar) molecule.

What causes green mouldy bread?

a) Aspergillus fungi

b) Algae

c) Penicillium fungi
