Difference between spermatid and spermatozoa:

	Spermatid	Spermatozoa
1.	These are immature male sperms produced by meiosis from spermatogonia.	They are mature, differentiated, and generated as a result of the spermiogenesis process.
2.	They have a circular form.	These are longer and have a tail.
3.	They can be found close to the walls of seminiferous tubules.	They are found in the center of the seminiferous tubules.
4.	They have Golgi.	There is no Golgi apparatus.
5.	They are unable to fertilize an egg.	They have the ability to fertilize the egg.
6.	Their nuclei are big and spherical.	The nucleus is elongated and circular.
7.	They are motionless.	They have the ability to move.
