Answer to Question #26029 in Biochemistry for hftckutf

Question

why is the size of a virus and bacteria importany

Answer 1

Bacterial cells and viruses do not have completely a nucleus, the inner membranes. Therefore, they need a very small cell size to regulate its ratio between the surface area and volume. Moreover, the small size of bacteria as well as virus permits to occupy their own environmental niche (for example, being extracellular and intracellular parasites).
