Understand the Problem
The question is asking about the structures that initiate microtubule growth during the fertilization process in sperm and egg cells. It presents multiple-choice answers related to cellular structures, aiming to identify the correct one responsible for initiating microtubule growth.
Answer
Centrosome
The centrosome initiates microtubule growth during fertilization.
Answer for screen readers
The centrosome initiates microtubule growth during fertilization.
More Information
During fertilization, the centrosome plays a key role by initiating and organizing the formation of microtubules, which are crucial for the union of the sperm and egg nuclei.
