Question

What occurs when multicellular organisms (Humans) grow and develop?

A. cell increase in numbers
B. Individual cells grow larger
C. Cells decrease in size
D. Cells decrease in numbers

Answer 1

A. cell increase in numbers

Step-by-step explanation:

One of the differences between unicellular and multicellular organisms is that by dividing cells, unicellular organisms multiply and multicellular organisms grow. As a multicellular organism grows, the number of its cells increases.

By growth, we mean an increase in the number of cells and an increase in the whole organism. Development refers to the changes that that organism goes through.
