What is a gamete simple definition?

gamete, sex, or reproductive, cell containing only one set of dissimilar chromosomes, or half the genetic material necessary to form a complete organism (i.e., haploid). … During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.

What is a gamete kid definition?

Kids Encyclopedia Facts. A gamete is a specialized sex cell that fuses with another gamete during fertilization (conception) in organisms that reproduce sexually. Gametes are produced by germ cells.

What is the best definition of a gamete *?

The definition of a gamete is a reproductive cell that has a single set of unpaired chromosomes and that can join with another cell to reproduce. … Animal egg and sperm cells, the nuclei carried in grains of pollen, and egg cells in plant ovules are all gametes.

What is a gamete example?

In short a gamete is an egg cell (female gamete) or a sperm (male gamete). … This is an example of anisogamy or heterogamy, the condition in which females and males produce gametes of different sizes (this is the case in humans; the human ovum has approximately 100,000 times the volume of a single human sperm cell).

What is gamete in plants?

Gametes can be described as sex cells of plants. Like humans, plants have sperm and egg cells that need to fuse in order to produce a zygote, or fertilized egg. Unlike humans, however, plants produce both types of these cells. Male and female gametes and their definition.

What are somatic cells explain?

A somatic cell is any cell of the body except sperm and egg cells. Somatic cells are diploid, meaning that they contain two sets of chromosomes, one inherited from each parent. Mutations in somatic cells can affect the individual, but they are not passed on to offspring.

Is a gamete a specialized cell?

A gamete is a specialized reproductive cell. It usually has half as many chromosomes in its nuclei as body (somatic) cells.

What is mitosis simple?

Mitosis is a process where a single cell divides into two identical daughter cells (cell division). … The major purpose of mitosis is for growth and to replace worn out cells.

What is sperm Class 8?

A sperm is single cell with all the usual cell components like nucleus, cytoplasm and cell membrane. The nucleus of sperm cell is tightly packed in its head. … The term sperm is the short form of the word spermatozoan. Eggs or ova or ovum. Eggs are larger than the sperms.

What are gamete types?

In certain organisms, like humans, there are two morphologically distinct types of gametes: (1) the male gamete (i.e. sperm cell) and (2) the female gamete (i.e. ovum). The male gamete is smaller in size and motile whereas the female gamete is several times bigger and non-motile.

Is a zygote a gamete?

Gamete refers to the individual haploid sex cell, i.e, the egg or the sperm. Zygote is a diploid cell formed when two gamete cells are joined by means of sexual reproduction.

What is Gametophyte in biology?

A gametophyte (/ɡəˈmiːtəfaɪt/) is one of the two alternating multicellular phases in the life cycles of plants and algae. It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. The gametophyte is the sexual phase in the life cycle of plants and algae.

What is a gamete formation?

Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.

How many chromosomes does a gamete have?

In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number.
