Question

Quizplus · Accepted Answer

The zona pellucida and corona radiata both have receptors for sperm cells. The zona pellucida is a thick glycoprotein layer surrounding the plasma membrane of the ovum, while the corona radiata is an outer layer of cells surrounding the zona pellucida. Both of these layers help to protect the ovum and provide support for the fertilization process.
