8.2 Cell Growth and
Reproduction
Part 1. Cell Growth
Cell Growth

What limits the size of a cell?
Cell Growth
What limits
the size of a cell?
1. Diffusion is slow

Day 7
Cell Growth

What limits the size of a cell?
1. Diffusion is slow
2. DNA takes time to copy
instructions for building proteins
Cell Growth

What limits the size of a cell?
1. Diffusion is slow
2. DNA takes time to copy instructions for
building proteins
3. Surface area to volume ratio is low
when a cell gets too big
Cell Reproduction


Before they get too big to function,
cells divide
Two cells identical to the original are
produced
Cell Reproduction



Chromosomes – structures that
contain genetic material
DNA coils up into chromosomes just
before cell divides
Chromatin –
uncoiled DNA
The Cell Cycle



The sequence of
growth and
division of a cell
Growth period =
Interphase
Division into two
daughter cells
= Mitosis
