Mitosis ,[object Object],Cell process in which the nucleus divides to form two nuclei identical to each other, and identical to the original nucleus, in a series of steps (prophase, metaphase, anaphase, and telophase)

Mitosis allows for growth and replaces worn out or damaged cells.

Asexual Reproduction A type of reproduction - fission, budding, and regeneration - in which a new organism is produced from one parent and has DNA identical to the parent organism.

Asexual Reproduction ,[object Object],[object Object],[object Object]

Sexual Reproduction A type of reproduction in which two sex cells, usually an egg and a sperm, join to form a zygote, which will develop into a new organism with a unique identity.

Sexual reproduction results in a great variety, or diversity, of offspring.
