Cell Division

Cell Division. Reproduction . How do organisms grow?. They increase both in size by increasing both the number and size of cells. Cell Cycle. The regular sequence of growth and division that cells undergo. Each new cell from the division is a:. Daughter cell.

Cell Division

Cell Division. Chromosomes. Are made of DNA Each chromosome consists of sister chromatids attached at a centromere. Cell Cycle. During the cell cycle, a cell grows, prepares for division, and divides to form 2 daughter cells, each with each of which then begins the cycle again.

The Cell Cycle

The Cell Cycle. Making new cells for growth and replacing old dying cells. Interphase. 95% of the cell cycle G1 -Cell grows to mature size S -DNA replicates G2 -Prepares for Cell division DNA is not in chromosomes yet. Interphase. Draw a picture of this phase. Mitosis: prophase.

Meiosis and Mitosis

Meiosis and Mitosis. Carly, Grace, Kellen, Emma. Meiosis. Produces Haploid gametes (sperm and egg cells) Reduced genetic material by half Used in sexual reproduction. Mitosis. Creates diploid cells (not sex cells) Daughter cells are identical to the mother cells Used for growth and repair.
