Cell Cycle

A repeating sequence of cellular growth and division during the life of a cell

1

A repeating sequence of cellular growth and division during the life of a cell

Cell cycle

2

Interphase

Phase where the cell prepares for division and is not dividing

3

Phase where the cell prepares for division and is not dividing

Interphase

4

Cell Division

Made up of mitosis and cytokinesis

5

Made up of mitosis and cytokinesis

Cell division

6

Mitosis

The process of dividing the nucleus in two daughter nuclei

7

The process of dividing the nucleus in two daughter nuclei

Mitosis

8

Cytokinesis

The process of separating the organelles and cytoplasm

9

The process of separating the organelles and cytoplasm

Cytokinesis

10

G1

The cell grows rapidly as the cell builds more organelles - takes up most of the cells life - the first gap phase

11

The cell grows rapidly as the cell builds more organelles - takes up most of the cells life - the first gap phase

G1

12

S

Where the cells DNA is copied - the synthesis phase

13

Where the cells DNA is copied - the synthesis phase

S

14

G2

Where the cell continues to grow and prepares to divide - micro tubes are formed - the second gap phase

15

Where the cell continues to grow and prepares to divide - micro tubes are formed - the second gap phase

G2

16

Microtubules

Made of protein fibers and will help with division - formed in the G2

17

Made of protein fibers and will help with division - formed in the G2

Microtubules

18

The phases of mitosis

Prophase
Metaphase
Anaphase
Telophase

19

Prophase

- chromosomes condense
- nuclear membrane breaks down
- the spindle forms
- centrosomes and centrioles appear

20

- chromosomes condense
- nuclear membrane breaks down
- the spindle forms
- centrosomes and centrioles appear

Prophase

21

Metaphase

- chromosomes are condensed
- nuclear membrane dissolves
- chromosomes line up along the equator
- spindle fibers link between the centromere of each chromosome and the poles

22

- chromosomes are condensed
- nuclear membrane dissolves
- chromosomes line up along the equator
- spindle fibers link between the centromere of each chromosome and the poles

Metaphase

23

Anaphase

- spindle fibers shorten
- chromatids move toward opposite poles and the spindle fibers shorten

24

- spindle fibers shorten
- chromatids move toward opposite poles and the spindle fibers shorten

Anaphase

25

Telophase

- nuclear envelopes form around the genetic material at each pole of the cell
- chromosomes uncoil and change back to their original form
- spindle and spindle fibers disappear, and mitosis is complete

26

- nuclear envelopes form around the genetic material at each pole of the cell
- chromosomes uncoil and change back to their original form
- spindle and spindle fibers disappear, and mitosis is complete

Telophase

27

Spindle

Structures made up of microtubules, that help the chromotids move during division

28

Cell plate

Forms between two daughter cells, separating them
