What is the difference between ova and sperm

Mitochondria is centrally located in this cell. Mitochondria is scattered in the cytoplasm of the cell. Amount of Cytoplasm. Cytoplasm is present in very small amounts in sperm cells. Cytoplasm is present in large amounts in the egg cell or the ovum. Nucleoplasm is absent in the cell. Nucleoplasm or the germinal vesicle is present in the egg cell.

Type of Chromosomes. Sperm cells contain X or Y chromosomes. Egg cells contain only X chromosomes. Centrioles are present in the sperm cell. Centrioles are absent in the sperm cell. Where are they produced? Sperms are produced in the testes, male reproductive organ. Ovum is produced in the ovary which is a female reproductive organ. A sperm is segmented into head, neck and tail.

Ovum has no such segmentation or similar structure. One spermatogonium results in the formation of four sperms. One oogonium results in the production of only one ovum. A sperm cell is surrounded by a plasma membrane.

An ovum cell is surrounded by egg envelopes. Differences Sperm Ovum Definition It is the male gamete or male reproductive cell. Related Concepts You have authorized LearnCasting of your reading list in Scitable.

These are also known as egg cell, oocytes. Ovum is round in shape and does not require the microscope to be seen and are visible through naked eyes. As the ovum has the large amount cytoplasm, they are said to be the largest cell in the anatomy of the human.

Their size varies from 0. The volume of the cytoplasm is so high, that nucleus is found dissolved in it. Though these cells are non-motile. Oogenesis is the process of producing ovum. Even after so many dissimilarities between both types of cells sperm and ovum , fuse into each other at the time of conception.

Difference between the two cells is prevalent. These two cells sperm and ovum are though significantly opposite cells regarding their origin, purpose, and nature. But these cells play their vital role at the time of conception, where the egg cell and ovum fuse to form.

The zygote. It is said that there is apart from these two cells, there is no such cell which combines and fit together to form the new diploid cells. Your email address will not be published.

Key Differences Between Human Sperm and Ovum Following are the difference between Human Sperm and Ovum: Sperm is the male gamete which is long, motile, flagellated cell and is differentiated into head, neck, middle piece and tail, though they are comparatively smaller in size.

Ovum is the female gamete, where the cells are rounded spheres and non-motile, though not differentiated into different parts, and the cells are larger in comparison to the sperm cell.

Mitochondria forms a spiral and are compactly arranged in the middle piece in the sperm, but in the ovum, mitochondria are scattered in the cytoplasm.

Cytoplasm is present in small amount in sperm as compare to the ovum. The nucleus is condensed with no nucleoplasm and contains X or Y chromosomes in Sperms along with centrioles, while Ovum contains nucleoplasm called as germinal vesicle and contains only X chromosome, centrioles are absent.

Sperms are produced in the testes, where four sperms are formed from one spermatogonium, whereas Ovum are produced in ovaries, and only one ovum is formed from one oogonium.
