Surface Area
: the amount of 'covering' of the object.
Volume
: the amount of space inside the object.
To find the
surface
area
, you multiple the L * W * the number of sides.
To find the
volume
, you multiply the L * W * H.
The
higher
the surface area and the
lower
the volume is the faster the cell fills up.
Cells are small because being
big
to too hard to
live.
Some cell growth limitations are
information
crisis
and
traffic
problems.
Information
Crisis
: too many demands placed on
DNA.
Traffic
Problems
: the volume grows too fast relative to
surface
area
,
moving
nutrients
and
waste
inefficient.
Some large cells have unusual structures to maintain a
high
surface
area
to
volume
ratio.
