24
Q

major functions for Mitosis

A

development of an individual from a fertilized egg

Replacement of old or damaged cells

25
Q

Prophase

A

-chromosomes condense
-spindle forms and migrate to opposite end of cell

26
Q

Prometaphase

A

-nuclear membrane breaks down
-spindle grows and attaches to centromere

27
Q

Metaphase

A

-spindle completely formed
-chromosomes line up along the middle of the cell (metaphase plate)
-Nuclear membrane is dissolved

28
Q

Anaphase

A

-centromere of each chromosome separate
-Single chromosomes are pulled by their centromeres

29
Q

Telophase in plant cells

A

-single chromosomes unravel
-nuclear envelope begins to form
-cell plate forms between cells until they separate

30
Q

Telophase in animal cells

A

-chromosomes begin to unravel
-nuclear envelope begins to form
-cleavage furrow forms and pinches the cells till they come apart
