Verified step by step guidance

Understand the concept of cleavage: Cleavage is a series of rapid mitotic divisions that occur in the early embryo, resulting in smaller cells called blastomeres.

Recognize the importance of surface area to volume ratio: As cells divide and become smaller, their surface area to volume ratio increases. This is crucial for efficient nutrient uptake and waste removal.

Analyze the options given: Evaluate each option to determine which one correctly describes a benefit of smaller cells during cleavage.

Consider the biological implications: Smaller cells with a higher surface area to volume ratio can more effectively exchange materials with their environment, which is vital for cell survival and function.

Conclude with the correct reasoning: The increased surface area to volume ratio is the key benefit of cells getting smaller during cleavage, as it enhances the efficiency of nutrient uptake and waste elimination.
