For fertilization to occur,many sperm are needed to
A) break down the cell membrane of the oocyte
B) activate the polar bodies
C) stimulate the final division of the oocyte
D) separate the cells of the corona radiata so a single sperm can enter
E) destroy the polar bodies so they don't use nutrients

Question

Quizplus · Accepted Answer

The corona radiata is a layer of follicle cells surrounding the oocyte that must be penetrated by sperm in order for fertilization to occur. Many sperm are needed to break down this layer and separate the cells, allowing a single sperm to penetrate and fertilize the oocyte. Option A is incorrect because the sperm do not break down the cell membrane of the oocyte. Option B is incorrect because polar bodies are non-functional and do not require activation. Option C is incorrect because sperm does not stimulate the final division of the oocyte. Option E is incorrect because the polar bodies do not use nutrients.
