MITOSIS

Page 5: The Cell Cycle & Cell Division. The Cell Cycle Cycle

Mitosis

The process of cell division which results in the production of two daughter cells

from a single parent cell.

The daughter cells are identical to one another and to the original parent

cell.

Page 6: The Cell Cycle & Cell Division. The Cell Cycle Cycle

Mitosis can be divided into stages

• Interphase

• Prophase

• Metaphase

• Anaphase

• Telophase & Cytokinesis

Page 7: The Cell Cycle & Cell Division. The Cell Cycle Cycle

InterphaseThe cell prepares for division

• Animal Cell – DNA replicated– Organelles replicated– Cell increases in size

• Plant Cell– DNA replicated– Organelles replicated– Cell increases in size

ProphaseThe cell prepares for nuclear division

• Animal Cell– Packages DNA into

chromosomes

• Plant cell– Packages DNA into

chromosomes

MetaphaseThe cell prepares chromosomes for

division• Animal Cell

– Chromosomes line up at the center of the cell

– Spindle fibers attach from daughter cells to chromosomes at the centromere

• Plant Cell– Chromosomes line up

at the center of the cell– Spindle fibers attach

from daughter cells to chromosomes at the centromere

AnaphaseThe chromosomes divide

• Animal Cell– Spindle fibers pull

chromosomes apart– ½ of each

chromosome (called chromotid) moves to each daughter cell

• Plant Cell– Spindle fibers pull

chromosomes apart– ½ of each

chromosome (called chromotid) moves to each daughter cell

TelophaseThe cytoplasm divides

• Animal Cell– DNA spreads out– 2 nuclei form– Cell wall pinches in to

form the 2 new daughter cells

• Plant Cell– DNA spreads out– 2 nuclei form– New cell wall forms

between to nuclei to form the 2 new daughter cells
