Question
Cleavage leads to increase in cell size.
Correct Answer
Option B is the correct answer.
Detailed Explanation
This statement is false. Cleavage is the rapid series of mitotic divisions of the zygote. It results in an increase in the number of cells (blastomeres), but there is no overall growth. The total volume of the embryo remains the same, so the cells become progressively smaller with each division.
Hint
Does the embryo get bigger during cleavage, or does it just divide into more, smaller cells?
