Zona pellucida and corona radiata are protective covers seen around egg/ovum. Zona pellucida is non cellular while corona radiata is made up of cells.

Explanation:

Both the egg covers remain intact when egg is placed in the fallopian tube after ovulation. Sperm must penetrate through both before fertilising the egg.
