Question

What happens to the number of cells during cleavage?

a) Decreases
b) Stays the same
c) Increases
d) No change

Answer 1

During cleavage, the number of cells increases as the zygote divides into multiple cells without increasing in size.

Step-by-step explanation:

In cleavage, the number of cells increases. During cleavage, the zygote rapidly divides into multiple cells without increasing in size. These cells rearrange themselves to form a hollow ball called the blastula. As more cell divisions occur, the number of cells increases.
