Steps of mitosis

Question 1

List all the steps of mitosis in order

Answer 1

Interphase
Prophase
Metaphase
Anaphase
Telophase

Question 2

What happens in interphase for mitosis?

Answer 2

-cells don’t divide

chromosomes aren’t visible( they exist chromatin)

-chromosomes replicate during S phase resulting in sister chromatids attached at the centromere

Question 3

What happens in Prophase for mitosis?

Answer 3

• chromosomes are visible and shorten and thicken

• in animal cells, centrioles move to opposite ends of the cell and attach to SPINDLE FIBRES

• nuclear membrane disappears

Question 4

What happens in Metaphase for mitosis?

Answer 4

•Spindle fibres are attached to centromeres

centromeres move sister chromatids to middle of cell

Question 5

What happens in Anaphase for mitosis?

Answer 5

•Centromeres divide and become daughter chromosomes

daughter chromosomes move to the opposite side of cell

Question 6

What happens in Telophase for mitosis?

Answer 6

-Chromosomes are at opposite sides and lengthen,

-spindle fibres disappear nuclear

-nuclear membrane forms around each set of chromatin

•then cytokinesis (division of cytoplasm)

Question 7

what is cytokinesis in animals and plant cells? when does it occur

Answer 7

-CYTOKINESIS
•in animal cells cleavage furrow devolops pinching cell into two

•in plant cells, cell plate forms into a new cell wall

it is the last step after telophase
