2.3. Mitosis and Meiosis

The stage where two sister chromatids divide and chromosomes move to opposite poles

Anaphase and Telophase

Cytokinesis starts at the middle of the cell and moves outward

Plate formation

Cytokinesis starts at exterior of the cell moving inward until the cell divides

Cleaveage Furrow Formation

The union of teo sex cells

Fertilization

How many chromosomes that haploid cell has?

23

How many sets of chromosomes that a zygote cell have?

2 sets

The 2 sets of chromosomes of a zygote

Diploid Cell(2n), 46 Chromosomes

Formation of the sperm cell occurs in the testis

Spermatogenesis

Development of egg cell

Oogenesis

It occurs in the body cells, its final chromosome number is diploid,2n( 46 Chromosomes in humans) and for growth, development,repair and maintenance of tissues, asexual reproduction

Mitosis

It occurs in Sex cells, its final chromosome number Haploid,n(23 Chromosomes for humans),and uts function is gamete production needed for sexual reproduction

Meiosis

The gamete or sex cell formation among all male animals

Spermatogenesis
