Slide1
The Cell Cycle
Slide2The Cell Cycle
Cell Cycle - a cycle of growth, development, and division
This is how organisms grow, produce new cells, and replace old cells
The cell cycle occurs in 2 phases: Interphase and
Mitosis
Slide3The Cell Cycle: Interphase
Interphase
– the period of the cell cycle where cell
growth
and development takes
place
Slide4The Cell Cycle: Mitotic Phase
Mitosis – division of the nucleus and the cell.
After a cell divides, the new cell is called a daughter cell.
There are 4 phases of
mitosis
Slide5The Cell Cycle:
Mitosis
The first phase of mitosis is
PROPHASE
In prophase,
the
nucleus breaks
open and the chromosomes (DNA) are freed
Slide6Slide7The Cell Cycle: Mitotic Phase
The second phase of mitosis is METAPHASE
In metaphase, all of the
chromosomes
line up in the middle of the cell
Slide8Slide9The Cell Cycle: Mitotic Phase
The 3
rd
phase of Mitosis is ANAPHASE
In anaphase, the chromosomes begin to split and travel to opposite sides of the cell.
Slide10Slide11The Cell Cycle: Mitotic Phase
The 4
th
phase of mitosis is TELOPHASE
In telophase, a new nucleus forms around the chromosome halves on each side of the cell
Slide12Slide13The Cell Cycle: Mitotic Phase
After the 4 phases of mitosis take place, cytokinesis occurs
Cytokinesis
is the splitting of the entire cell.
Slide14Slide15The Cell Cycle: Mitotic Phase
Cell division results in cell reproduction, growth of organisms, replacement of cells, and cell repair.
