mitosis and meiosis

Haploid

A cell with one set of chromosomes (has 23 chromosome)

Diploid

A cell with two sets of chromosomes (has 46 chromosomes)

Mitosis

Growth, repair, and maintenance of body cells.

Mitosis Starting Cell

1 diploid (46 chromosomes).

Mitosis ending

2 diploid cells (each with 46 chromosomes)

Prophase (mitosis)

Chromosomes condense, spindle forms.

Metaphase (mitosis)

Chromosomes line up in the middle.

Anaphase (Mitosis)

Sister chromatids separate to opposite poles.

Telophase (mitosis)

Nuclear envelope reforms, chromosomes uncoil.

Cytokinesis (mitosis)

Cytoplasm divides → 2 identical diploid daughter cells.

what type of cells does mitosis create

Body cells (Somatic)

What type of cell Meosis make

Gametes (sperm-male, egg-female)

Meiosis

Produce gametes (sperm/egg) with half the chromosome number.

Starting Cell (meiosis)

1 diploid (46 chromosomes)

Ending Cells (meiosis)

4 haploid (23 chromosomes each)

Prophase I (meiosis)

Crossing over (genetic variation)

metaphase I (meiosis)

Homologous pairs line up in the middle.

Anaphase l (meiosis)

Homologous chromosomes separate

Telophase l & Cytokinesis (meiosis)

2 haploid cells formed.

Prophase II (meiosis)

New spindle forms.

Metaphase II (meiosis)

Chromosomes line up in the middle.

Anaphase II (meiosis)

Sister chromatids separate

Telophase II & Cytokinesis (meiosis)

4 haploid gametes formed.
