Difference between male and female gamete​
Inga [223]

Answer:

The male gamete is smaller in comparison to that of the female gamete.

The male gamete is conical from the front while the female gamete is spherical.

The cytoplasm in the male gamete is less in comparison to that of the female gamete.

The male gamete can move with the help of the tail while the female gametes are immobile and do not have any tail or flagella present.

The number of mitochondria present in the sperm is less than the number of mitochondria present in the ovum.

The male gamete has acrosome present in the head region that contains enzymes for dissolving the membranes present around the ovum. The ovum does not contain such digestive enzymes.
