Which statement best explains how the needs of a unicellular organism are met?
a) cell parts do everything
b) all cells must work together
c) most tissues work together
d) specialized cells work together

a) cell parts do everything

Explanation:

Firstly, a unicellular organism is an organism with only one cell. This means that there would be no specialization or differentiation of cells. Also, this means that tissues, which Is the collection of similar cells, cannot be formed.

However, in its single cell, the unicellular organism will contain cell parts or organelles, which are organ-like structures that perform specific task in the cell. Therefore, cell parts in the single cell will do everything.
