Which Process Is Responsible For The Growth And Repair Of Human Tissue

Mitosis vs Meiosis

Mitosis and meiosis are both processes by which cells reproduce, just there are distinct differences between the 2. While new cells are generated during mitosis, meiosis is a special type of cell partitioning that produces sex cells for reproduction. The ii processes were discovered by dissimilar scientists. Meiosis was discovered past German biologist Oscar Hertwig while German dr. Walther Flemming is credited with the discovery of mitosis.

The Purpose of the Reproduction

Only sexually reproductive organisms use meiosis. The function of the process is to produce sexual activity cells and to repair genetic defects in germ line cells (the sexual practice cells).

Both sexual and asexual organisms get through the procedure of mitosis. It happens in the cells of the body known as the somatic cells and produces cells related to growth and repair. Mitosis is essential for asexual reproduction, regeneration, and growth. It does not brand sex cells or gametes.

Number of Girl Cells

In meiosis, four haploid cells containing half the corporeality of chromosomes are produced at the end of the process.

Alternatively, two diploid cells, containing two sets of chromosomes, are produced equally a result of mitosis.

Limerick of the Daughter Cells

The daughter cells produced at the end of meiosis are completely unlike from the original parent cell and they include a mix of both the maternal and paternal genes, leading to genetic variety during sexual reproduction.

The girl cells created in mitosis are genetically the aforementioned as the original parent cell.

Phases of Reproduction of the Cells

Meiosis has two phases for the reproduction of cells which results in at that place beingness two cell divisions. The first phase includes prophase I - during which the well-nigh important events of meiosis occur, metaphase I, anaphase I, telophase I, and cytokinesis. During the 2nd stage, these processes repeat again with the cells that were formed at the finish of the offset phase.

In mitosis, the cells dissever simply once and this is via one phase which includes steps such as prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis.

Pairing of Homologues

Meiosis involves the pairing of homologues, chromosomes like to other chromosomes, whereas mitosis involves no pairing of homologues.

Differences in Anaphase

During the anaphase of meiosis, the sis chromatids exercise non separate. In anaphase I, the chromosomes are double-stranded and in Anaphase II, they are single stranded.

During anaphase in mitosis, the sis chromatids do separate at the centromeres and the chromosomes are single stranded.

Differences in Telophase

In mitosis, the spindle fibres recede fully during telophase, simply this is non the case with telophase I of meiosis. Also the nucleoli reappear in mitosis but not in meiosis.

Mixing of Chromosomes

In meiosis, the chromosomes cantankerous over causing mixing. Mitosis, on the other paw, does non involve crossing over of the chromosomes.
