What is the difference between sperm and egg cells

The cell consists of a large amount of cytoplasm in which the nucleus dissolves until just before conception. The sperm has an oval head on the top and has a rigid middle with a slimly tail in the back to allow it to swim.

It is straight in shape. Egg cells have a short life span. If an egg cell is not fertilized 12 to 24 hours after its release from the ovary, it will dissolve.

Sperm cells have a longer life span. Once ejaculated in the female womb they can survive for days. Egg cells contain cytoplasm, which allows them to be active internally. After the nucleus is released from the follicular cell, it becomes less mobile.

Sperm cells are active and externally mobile. They use their tails to swim against the stream of fluid in the oviduct to the fallopian tube. Difference between Egg Cells and Sperm Cells. Egg Cells Sperm Cells Anatomy The egg cells have a nucleus that is surrounded by cytoplasm, which is guarded by the zona pellucid and the follicular cells.

Produced in Egg cells are produced in the ovary of a female human being. Sperm cells are produced in the testicles of a male human being. Size Larger compared to sperm cells.

Approximately 0. Appearance The egg cell is one of the largest human cells in the body. Shape Round, oval or a circle. Produce in numbers Only a single egg cell is produced during once menstruation cycle.

Millions of cells are released during a single ejaculation. Temperature Requires warm body temperature for sustenance. Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm.

Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.

During meiosis, a diploid parent cell, which has two copies of each chromosome, undergoes one round of DNA replication followed by two separate cycles of nuclear division to produce four haploid cells.

These cells develop into sperm or ova. The nucleus is small, with the small quantity of cytoplasm. The cell is divided into various parts like the head, neck, middle piece and long tail with some mitochondria. The process by which sperms are produced is called as spermatogenesis. Ovum is the female reproductive cell. 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.
