Mitosis and meiosis similarities

The alternation of generations in the life cycle of a plant includes the diploid and haploid multicellular stages. diploid and haploid are copies of the chromosomes. The spores in the plant is unicellular and when they start dividing through mitosis, it produces identical cells. These identical cells are all haploid. Haploid stages contain one set of chromosome from either of the parent. These identical cells create a multicellular system called the gametophytes. A gametophyte is the haploid multicellular stage in the life cycle of a plant. The gametophyte makes the gametes. These gametes are responsible for sexual fertilization. It takes place when a sperm (male gametes) from the male fuses into the egg cell (female gametes) of the female. The formation of both male and female gametes creates a diploid zygote. Diploid stages contain one set of chromosome from each parent. This is where the sporophyte comes in. A sporophyte is the diploid multicellular stage in the life cycle of the plant. It now contains the two sets of chromosomes from each parent.

The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.
