Difference between ovum and zygote

WebAnswer: Explanation: When a sperm comes in contact with the zona pellucida layer of the ovum, it induces changes in the membrane of the ovum to block the entry of additional sperms. This thus prevents the polyspermy and ensures that only one sperm can fertilise an ovum. What is the difference between fast block and slow block polyspermy?

Primary organs of the human reproductive system or the primary sex organs of males are a pair of testes and in females, a pair of ovaries. Primary sex organs produce gametes— sperms in males and ovum in females. WebFertilization is a fusion of male and female gametes to produce a zygote. A zygote is a newly fertilized egg that contains the necessary genetic information to make offspring. For example, fertilization takes place when a sperm fuses with an ovum, forming a single cell that can develop into an embryo.
