biology - mitosis and cytokinesis

what are the 4 phases of mitosis

1. Prophase

2. Metaphase

3. Anaphase

4. Telophase

mitosis

division of the nucleus

which stage of mitosis is the largest

prophase

what 3 things happen in prophase

1. chromatin forms into chromosomes

2. nucleus and nuclear membrane disappear

3. spindles form

spindles

the protein fibers that form in between spindle poles and centrioles

what are spindles responsible for

moving chromosomes in mitosis

what 2 things happens in metaphase

1. chromosomes attach to the spindles 2. chromosomes move to the center of the cell

what two things happen in anaphase

1. centromeres divide

2. sister chromatids separate and move away

what 3 things happen in telophase

1. new nuclear membranes and nucleolus forms

2. spindles brake down

3. chromosomes go back into chromatin

cytokinesis

division of the cytoplasm into 2 separate cells

cytokinesis in an animal cell

the cell membrane is drawn inward til it divides

cytokinesis in plant cell

a cell plate is formed between the 2 nuclei, splitting the cell in 2

what does the cell plate become

the new cell wall

what is the end result of cytokinesis

2 genetically identical daughter cells
