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 cells develop into sperm or ova.

Are sperm cells male or female?
Sperm is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, female reproductive cell and a smaller, male one).
How are egg and sperm cells different from other cells?
Like a sperm cell, the egg contains a nucleus with half the number of chromosomes as other body cells. Unlike a sperm cell, the egg contains a lot of cytoplasm, the contents of the cell, which is why it is so big. The egg also does not have a tail.
How many chromosomes does a sex cell egg or sperm have?
Each "human body cell" has 46 chromosomes. But human sex cells have 23 unpaired chromosomes in each cell.
What is a egg cell?
ovum, plural ova, in human physiology, single cell released from either of the female reproductive organs, the ovaries, which is capable of developing into a new organism when fertilized (united) with a sperm cell. ... A hollow ball of cells, the follicle, encompasses each ovum.
How many chromosomes are in a sperm cell?
Chromatin is packed in a specific way into the 23 chromosomes inside human spermatozoa. The differences in the chromatin organization within sperm and somatic cells chromosomes are due to differences in the molecular structure of the protamine DNA-complexes in spermatozoa.
What are sperm and egg cells called?
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.
What is the difference between egg and sperm production?
The most obvious difference: a sperm cell is a reproductive cell of males while egg cells are of females. ... Both egg cells and sperm cells undergo meiosis. Sperm cells are developed in the epididymis, while egg cells develop in the woman's ovaries. An egg cell is bigger than a sperm cell.
What is the sperm cell?
sperm, also called spermatozoon, plural spermatozoa, male reproductive cell, produced by most animals. ... The sperm unites with (fertilizes) an ovum (egg) of the female to produce a new offspring. Mature sperm have two distinguishable parts, a head and a tail.
How many chromosomes are in an egg cell?
The final product of meiosis is an egg cell with 23 chromosomes.
What is the name of male sex cell?
In the human reproductive process, two kinds of sex cells, or gametes (pronounced: GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (pronounced: ZYE-goat).
What is sperm structure?
Sperm is composed of a head, neck, middle piece and tail. Whole body of sperm is enclosed by plasma membrane. The head contains as enlongated haploid nucleus, the anterior portion is covered by a cap-like structure called as acrosome. This acrosome is filled with enzymes that help fertilisation of the ovum.
How are sperm cells produced?
Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
How many chromosomes are in a fertilized egg?
Healthy humans have 46 chromosomes, 23 from the sperm and 23 from the egg. An embryo with the wrong number of chromosomes is usually miscarried, or develops disorders such as Down's syndrome, which is caused by an extra copy of chromosome 21.
