Web23 jul. 2024 · Meiosis is the process of cells splitting into four haploid cells thus reducing the chromosome number by half in each cell. They also give rise to gametes in the human body but plant spores in plants. Meiosis occurs in the sex cells so the sperm and egg cells in the human body to create even more of themselves. http://ib.bioninja.com.au/standard-level/topic-3-genetics/33-meiosis/stages-of-meiosis.html

The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up … WebIn meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity.

Web23 apr. 2024 · When a living thing needs new cells, a process of cell division called mitosis begins. The five stages of mitosis are interphase, prophase, metaphase, anaphase and telophase. Mitosis is responsible for a single cell (a fertilized human embryo) developing into a human body with five trillion cells. WebInterphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). A cell in interphase is not simply quiescent.
