Bio 9 - Unit 5 (Mitosis)

Interphase

Cell grows, number of organelles increase, DNA copied

Prophase

Nuclear membrane disappears, DNA condenses into duplicated chromosomes, centrioles produce spindle fibre that starts to attach onto the centromeres

Metaphase

Chromosomes align at the cell's equator and spindle fibers attach to their centromeres

Anaphase

Sister chromatids separate and are pulled to opposite poles of the cell by spindle fibers.

Telophase

the final stage of mitosis where chromosomes de-condense, the nuclear membrane re-forms around each set of chromosomes, and the cell prepares to divide.

Cytokinesis

Cytoplasm and organelles are divided, two separate cells form

Mitosis for plant cells

Cell plate made of vesicles spread in the centre between the nuclei and separates to become the cell wall
