CELL DIVISION
2. Large cells have difficulty
transporting enough nutrients across
their membrane
Cells are limited in size by their
SURFACE AREA and VOLUME ratio
WHY DO CELLS DIVIDE?
3. Process where a cell splits into two
identical daughter cells. It occurs it
two main phases.
Each new cell has exactly the same
genetic material (DNA) as the cell
that produced it.
CELL DIVISION
4. Cell division is the basis of
life itself; it is how animals
grow and reproduce.
CELL DIVISION
5. 1. The reproduction of an entire unicellular
organism
2. The growth and repair of tissues in
multicellular animals, and
3. the formation of gametes (eggs and sperm)
for sexual reproduction in multicellular animals
THREE MAIN FUNCTIONS
6. Mitosis is
the division
of the
nucleus
MITOSIS VS. CYTOKINESIS
Cytokinesis is
the division of
the cytoplasm
7. Made of DNA,containing the cell's
genetic code
Found in Nucleus
Each chromosome has a matching pair,
homologous pair
Number depends on organism
CHROMOSOMES
10. Nucleus divides, ensuring
each new cell has the exact
number of chromosomes
as parent
MITOSIS
11. G1 - first growth (gap) phase
Synthesis - DNA makes a copy
G2 – second growth (gap)
phase, preparing for mitosis
INTERPHASE (LONGEST PHASE)
12. (technically not part of
mitosis, but it is included in
the cell cycle)
Cell is in a resting phase,
performing cell functions
INTERPHASE (LONGEST PHASE)
13. DNA replicates (copies)
Organelles double in number,
to prepare for division
INTERPHASE (LONGEST PHASE)
22. Division of the cytoplasm to form 2 new
daughter cells
Organelles are divided
Daughter cells are genetically identical
Cells return to interphase
Cytokinesis takes two forms, depening on
the cell
CYTOKINESIS
23. Cell pinches inward and then splits into two
ANIMAL CELLS
24. A new cell wall (called the cell plate) forms
between the two new cells
PLANT CELLS
