Cell Growth and Division
Cell division – when a cell produces two new
daughter cells
Cell division is …
-
Life Cycle of a Cell - Time Line
Interphase
(most of the cells life)
Mitosis
PMAT
Interphase
Cell
membrane
Nucleolus
(ball of DNA)
Cytoplasm
Nucleus
Inter
– meaning between
Active time between cell divisions
-
Nuclear
membrane
Mitosis
Cellular
process of passing on DNA
DNA (deoxyribonucleic acid) – code of cellular
instructions
P – Prophase
Mitosis occurs in four stages:
M – Metaphase
A – Anaphase
T - Telophase

Chromosomes reach opposite ends of cell

Two New Daughter Cells !!!
Daughter
cells are identical to their parent cells
