Are animal gametes produced by meiosis?
Gametes are produced by mitosis (not meiosis) and after fertilization a diploid zygote is created.
Which type of cell division do animal cells perform to produce a gamete?
Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.
What process produces gametes in animals?
meiosis
The process that produces haploid gametes is called meiosis. Meiosis is a type of cell division in which the number of chromosomes is reduced by half. It occurs only in certain special cells of an organism. In mammals, Meiosis occurs only in gamete producing cells within the gonads.
Which type of cell division produces gametes in animals and spores in plants?
In plants and animals In animals, meiosis produces gametes directly. In land plants and some algae, there is an alternation of generations such that meiosis in the diploid sporophyte generation produces haploid spores.
Is gamete cells mitosis or meiosis?
Mature male or female reproductive cells (sperm or ovum) containing half of the total number of chromosomes in a cell (i.e., humans have 46 chromosomes per cell; gametes would have 23). fused….Meiosis: Gamete formation.

Two cells made are genetically identical. | Four cells made are genetically different. |
Where does meiosis occur in animals?
In animals this occurs in the gonads (ovaries in females; testes in males). In plants this occurs in the archegonia in females and in the antheridia in males.
Does mitosis occur in animal cells?
Mitosis is the process in cell division by which the nucleus of the cell divides (in a multiple phase), giving rise to two identical daughter cells. Mitosis happens in all eukaryotic cells (plants, animals, and fungi).
What are gametes in animals?
The gametes in animals are sperm (male) and eggs (female). The gametes in flowering plants are pollen (male) and ovules (female). The offspring produced in sexual reproduction are genetically different to each other and to their parents.
Is meiosis a gamete?
Gametes, or reproductive cells, are produced in a special kind of cell division called meiosis. During this process the normal number of the cell’s chromosomes is reduced by half. Each gamete ends up with a copy of one chromosome from each pair.
Does mitosis occur in animals?
Does mitosis occur in animal cell?
Mitosis is a process where one cell divides to give rise to two identical daughter cells. The chromosomes are equally distributed in the two cells….What is the Difference between Plant Mitosis and Animal Mitosis?

It occurs only in the meristematic tissues. | It occurs in all the animal parts except the reproductive cells. |

What is meiosis in animals?
Meiosis is a process of reduction division in which the number of chromosomes per nucleus is halved and homologous chromosomes are separated. Gamete formation in animals is a typical example of an event in which meiosis plays a key role.
