During cleavage, what is false about cells?

Explanation

Let's evaluate each statement about cells during cleavage to determine what is false: a. Nucleocytoplasmic ratio remains unchanged: This statement is generally true. During cleavage, the zygote undergoes multiple rounds of cell division without significant cell growth. As a result, the ratio of nucleus to cytoplasm generally remains constant. b. Size does not increase: This statement is generally true. Cleavage involves rapid cell divisions without substantial cell growth, so the individual cells produced during this process are smaller than the original zygote. c. There is less consumption of oxygen: This statement is generally true. Cleavage is an anaerobic process, meaning it doesn't rely heavily on oxygen consumption. Instead, it primarily utilizes the existing nutrients stored in the egg. Correct Answer: b. Size does not increase. Summary: During cleavage, the nucleocytoplasmic ratio remains relatively unchanged, and there is less consumption of oxygen. However, the size of the cells does increase in terms of their number, but their individual size remains small. Therefore, the false statement is that "Size does not increase." Cleavage is characterized by rapid cell division without significant cell growth.
