(Cytokinesis)

67
Q

Name the hierarchy of cells

A

68
Q

What is mitosis?

A

Mitosis is the division of a cell nucleus to produce 2 identical cells

69
Q

What happens during the Prophase?

A

Chromosones condense and thicken. The cell membrane disappears

70
Q

What happens during the metaphase?

A

M for middle chromosomes line up along the middle

71
Q

What happens during the anaphase?

A

A for apart. Spindle fibres condense and shorten, dragging the chromatids to each end

72
Q

What happens during the Telophase?

A

T is for 2. The nuclear membrane reforms to make **2 **nuclei but it is still one cell.

73
Q

A

When bacteria make more copies of themselves through the process of mitosis

74
Q

What is it called when bacteria make more copies of themselves through the process of mitosis?

A

Binary Fission
