↑Cells
Interphase
- G1 Phase
- The cell grows and doubles in size, reproducing its organelles.
- What doubles in the ^1670442523570 g1 phase? ;; ^1670442541145Enzymes, Cytoplasmic organelle.
- S Phase
- Doubles the amount of DNA, doubles the amount of chromosomes.
- G2 Phase
- The mitochondria divides and chloroplasts divides as well, if it is a plant cell.

Mitosis
- Prophase - 2 copies of each chromatid, attached with a centromere. Formation of mitotic spindles + microtubules and the nucleus starts to dissipate.
- Chromatins
- One strand of DNA
- Chromatids
- Two strands of DNA
- Chromosomes
- Parts of full DNA
- Chromatins
- Prometaphase | Late prophase
- Nuclear membrane fragments and microtubules are in the nuclear area.
- The spindle is formed.
- It will seperate the chromosomes into Chromatids.
- Attaches to Chromatids
- Centrioles move
- Metaphase
- The chromosomes move towards the middle of the cell.
- Spindles attach to centromeres and sister chromatids.
- Centrioles connect the mitotic spindles to the edge of each cell.
- Anaphase
- Centromeres divide.
- The chromosomes split[1] and are brought to opposite sides of the cell to prepare for the whole cell to envelope in and split.
- Telophase
- The nucleus on each side starts to bring in the daughter chromosomes and start to reform their nuclear membranes. Chromosomes split back into chromatins.
- Where the two cell membranes start to form, it is called ;; Cleavage furrow
Cytokinesis
- Organelle split and goes into the new cell.
- In a {1:plant cell} a cell wall or {2:cell plate} generates to split the two.
