Cell growth and division

1
Cell growth and division

• Vocabulary

2
MITOSIS
process of cell division in which one cell
divides to form two identical cells
CYTOKINESIS
Breaking apart of the cytoplasm into 2 separate
cells with separate nuclei
3
CHROMATID
CHROMATIN
Threadlike substance in a nucleus that forms
proteins during mitosis
Pair of sister chromosomes
CENTROMERE
Sticky middle that keeps pairs of chromosomes
(chromatids) together
4
chromatin
Chromatid
Centromere
5
CENTRIOLE
a small, cylinder structure that appears during
prophase to pull the chromosomes apart
SPINDLE FIBER
A filament that extends inward from the poles of
a dividing cell
6
CELL CYCLE

• Sequence and growth of a cell
• 95 of cell cycle in Interphase
• 5 of cell cycle in Mitosis

INTERPHASE
The longest period of the cell cycle known as the
growth phase when the nucleus is not undergoing
division
7
PROPHASE
The first stage of mitosis during which the
nuclear membrane breaks down and thin strands of
chromatin form into chromosomes. They then pair
up with their sister chromosome creating
chromatids.
8
ANAPHASE
METAPHASE
 The stage of mitosis when the chromosomes move
and line up along the center or equator
The stage in mitosis in which the pairs of
chromosomes separate and move away from each
other to opposite ends of the cell.
9
TELOPHASE
 The final stage mitosis, where the separated
chromosomes reach opposite ends and form into 2
separate cells with their own nuclei
