Question

match each of the following structures in an ovum (egg) with the function it performs during fertilization. jelly coat sperm - binding receptors vitelline layer corticle granule nucleus

Explanation:

The jelly - coat binds to sperm during recognition. Sperm - binding receptors are involved in the attraction and contact phase between sperm and egg. The vitelline layer is involved in the cortical reaction. Corticle granules release contents during the cortical reaction to prevent polyspermy. The nucleus of the ovum contains a haploid set of chromosomes which will combine with the sperm's chromosomes during fertilization.

Answer:

Jelly coat: During recognition, bind to sperm
Sperm - binding receptors: During attraction and contact, bind sperm
Vitelline layer: During the cortical reaction, lift off the egg surface
Corticle granule: During the cortical reaction, release enzymes
Nucleus: Contains one set of chromosomes for genetic contribution
