What Is Mitosis,Amitosis And Meiosis?

 Mitosis: Mitosis is a type of cell division in which parent cell produces two daughter cells through a sequential nuclear division. This type of cell division produces daughter cells having equal number of chromosomes and identical genetic constitution like the parent cells.

Mitosis helps in growth and development of the body of an organism. Healing of wounds, repairing of lost parts etc. take place by mitosis. Unicellular organisms usually reproduce through the process of mitosis.

Amitosis :- Amitosis is a process of cell division in which the cell directly separates. Cytoplasm and nucleus are cut into two. No phases like mitosis and meiosis occur.

Meiosis :-  Meiosis is the reductional cell division in which diploid (double set) number of chromosomes is reduced to haploid (single set) number. Meiosis has two different phases – meiosis I and meiosis II. Meiosis I is reduction division which produces two haploid cells where as Meiosis II is the equational division which produces total of four haploid cells from the two resulting meiosis I cells by the process of mitosis.

During formation of male and female gametes in organisms meiosis occurs.

Amitosis is very  uncommon process in which nucleus & cytoplasm directly divides into two,chromosomes do not undergo any spindle formation where as in mitosis parent cell divides into two daughter cell. It is also known as equational division in which chromosomes undergo different stages to generate two daughter cells

Meiosis is the specialized kind of cell division that reduces the chromosome number by half (thus called reductional division) resulting in production of haploid daughter cells (gametes). It mainly takes place in the reproductive cells or se x cells.

Amitosis-Amitosis is a process of cell division in which the cell directly separates. Cytoplasm and nucleus are cut into two. No phases like mitosis and meiosis occur.it  has no mitosis.

Mitosis- division of cells from the same parent creating one identical daughter cell. This daughter cell contains the exact same genes as the parent cell. Most of the cells of an organism go through this division. Mitosis is a type of asexual reproduction, meaning it does not involve the combination of genes from two different cells.

Meiosis- reproduction of two gamete cells that combine to form a zygote resulting into four haploid (1n) cells. The four cells are not genetically identical. This form of reproduction is called sexual reproduction.
