TYPES OF CELLS:
DIPLOID
HAPLOID
Diagram showing the production of two diploid daughter cells via Mitosis
Diagram showing the production of four haploid daughter cells via Meiosis
NUMBER OF CHROMOSOMES:
46
NUMBER OF CHROMOSOMES:
23
Somatic cells (body cells) produced via Mitosis containing 46 Chromosomes (23 pairs)
EXAMPLE:
Skin cells, Red blood cells
Gametes produced via Meiosis containing 23 Chromosomes (half the number of Chromosomes in Somatic cell)
EXAMPLE:
Sex cells
