Answer:

The zona pellucida is formed as the follicle becomes a secondary follicle. The zona pellucida is a gelatinous membrane that surrounds the oocyte and spermatozoon during fertilization. It acts as an extracellular matrix for the embryo and spermatozoon to adhere to each other, and it also serves as a physical barrier between the oocyte and surrounding environment.

The zona pellucida consists of two layers: an outer layer called the basal lamina, which consists of collagen fibers arranged in parallel bundles

So the answer is true
