Question

Which is an advantage that single-celled organisms have compared to multicellular organisms?
a. They can reproduce very quickly by binary fission.
b. When one cell works the other cells benefit.
c. Increased size affects their ability to obtain nutrients.
d. Survival is dependent on other cells.

Answer 1

a. Single-celled organisms can reproduce very prolifically through processes such as binary fission. Whereas they only have to produce one cell, multi-celled organisms have to produce another multi-celled organism, which obviously takes a lot longer.
