Vedclass · Answer

(C) During the process of fertilization,the sperm head (containing the nucleus) enters the egg cytoplasm,while the tail and middle piece (containing mitochondria) are usually left outside.Therefore,the Assertion is correct.However,the Reason is incorrect because the egg has mechanisms to prevent polyspermy (the entry of more than one sperm). Once the first sperm enters the egg,the zona pellucida undergoes changes to block the entry of other sperm,ensuring that only one sperm fertilizes the egg.

Assertion : During fertilization,only the head of the spermatozoa enters the egg.
Reason : If several spermatozoa hit the egg at the same time,all can enter the egg.
