Life of the cell: the process of their growth.
Five phases of mitosis
Prophase - Chromosomes condense and Chromatids connect at centromeres. |
Metaphase - Chromatid pairs align at metaphase plate. |
Anaphase - Daughter chromosomes separate. |
Telophase - Nuclear envelopes reform. |
Cytokinesis - Division of the cytoplasm to form two identical daughter cells. |
Mitosis is the process of cell division which results
in the production of two daughter cells
from a single-parent cell.

Phases in Meiosis
Meiosis 1 |
Meiosis 2 |
Prophase 1 - Each chromosome duplicates and remains closely associated. These are called sister chromatids. |
Prophase 2 - DNA does not replicate. |
Metaphase 1 - Chromosomes align at the center of the cell. |
Metaphase 2 - Chromosomes line up at the center of the cell. |
Anaphase 1 - Chromosome pairs separate with sister chromatids remaining together. |
Anaphase 2 - Centromeres divide and sister chromatids move separately to each pole. |
Telophase 1 - Two daughter cells are formed with each daughter containing only one chromosome of the chromosome pair. |
Telophase 2 - Cell division is complete. |
Four haploid daughter cells are formed after the process.
