G1

Cell grow and functions normally

S

DNA is replicated

G2

cell grows more, checks for DNA errors, and preps for mitosis

Mitosis

division of cells

Prophase

Chromosomes condense; nuclear envelope breaks down

Metaphase

Chromosomes line up in the middle

Anaphase

sister chromatids are pulled apart

Telophase

New nuclear envelopes form

Cytokinesis

Cytoplasm divides, forming two identical daughter cells

Meiosis

special type of cell division that four genetically unique gametes, each with half the number of chromosomes to ensure that a fertilized cell will have the correct number of chromosomes

Gametes

sperm and egg

Haploid

chromosomes

Meiosis 1

homologous chromosomes pair up and swap genes and Paris are separated into two cells.

Meiosis II

sister chromatids split and produce four non-identical haploid gametes
