Sperm:
1. Sperms are produced in the testes.
2. Four sperms are formed from one spermatogonium.
3. It is differentiated into head, neck, middle piece and tail.
4. It has very small amount of cytoplasm.
5. Mitochondria form a spiral in the middle piece.
6. Sperm is motile and penetrates the ovum by releasing lysing enzymes (e.g., hyaluronidase).
Ovum:
1. Ova are produced in the ovaries.
2. Only one ovum is formed from one oogonium.
3. It is not externally differentiated into regions.
4. It has a large amount of cytoplasm called ooplasm.
5. Mitochondria are scattered in the ooplasm.
6. Ovum is non-motile.
