Cell
reproduces through a continuous sequence of growth and division known as the
cell cycle.
The cell
cycle has two main stages:
Growth
stage
-
Interphase
o Longest part of the cell cycle
o Cell performs its normal fuctions
o DNA is copied and duplicated in a
process call DNA replication.
o More organelles are duplicated.
Division
stage: it produces two genetically identical daughter cells.
-
Mitosis
o The division of the contests of the
nucleus (DNA is divided).
o The division of the rest of the cell
organelles (cytoplasm, cell membrane, ribosome…)
Timeline
The timing
of the cell and the lengths of the different phases depend on the type of cell
and its environment.
