The main difference between sperm and spermatid is that, while a sperm is a mature sex cell, the spermatid is still an immature cell.
To become a sperm, the spermatid will have to undergo a process known as spermiogenesis.
Both types of cells have many things in common; for example, they only contain half the chromosomes of the rest of the cells in the human body. However, they are also quite different.
Both types of cells are closely related, since the spermatid is the raw material to create new sperm.
The spermatid is a haploid cell; that is, it is a cell that only contains half the chromosomes of the rest of the cells in the human body. It is the precursor of male gametes, also known as sperm.
Spermatids are formed through a process known as meiosis, which occurs in the testes.
Although they are the same genetically as sperm, their appearance is very different: they resemble other animal cells, only with half the chromosomes.
Therefore, spermatids are circular in shape, with the appearance of a cell with all its organelles intact..
Once they undergo the process known as spermogenesis, they transform into proper sperm.
Sperm are male gametes: that is, the cells responsible for transmitting genetic information from the father to his descendants.
When they unite with an egg they are able to create a zygote, which will later develop into a new life.
Like spermatids, they have half the chromosomes of the rest of the cells in the human body, which is why they are known as haploid cells. However, their appearance and functionality are very different..
Sperm are elongated cells, divided into three clearly differentiated parts: a head (which contains DNA), a body, and a tail or flagellum to move in search of the egg. This aspect is acquired after spermogenesis.
While spermatids are large, round cells, with all their organelles still present, sperm are totally different from other cells in the body..
They have an elongated shape, divided into three different parts. They have also lost most of their organelles, with the exception of mitochondria.
The nucleus of the spermatid is large and rounded. In sperm, on the other hand, it is elongated and much smaller..
Mitochondria (the organelles that give cells energy) are dispersed in spermatids.
On the other hand, in sperm they are concentrated near the flagellum to provide it with greater mobility..
While spermatids are immobile, sperm are characterized by being able to move great distances thanks to the flagellum..
Sperm are the only cells that can fertilize an egg; spermatids do not have this ability.
