The surface area of a cell is
the total amount of space taken up by a cell
the area of a cell
the outer surface of the cell, the plasma membrane
a comparison between the surface area and the volume of the cell
The volume of a cell is
the cytoplasm in the cell
the outer surface of the cell
how loud the cell is
the total amount of space taken up by a cell, including all cellular contents
How is the surface area to volume ratio of a cell calculated
surface area plus volume
surface area divided by volume
surface area multiplied by volume
surface area minus volume
As a cell grows larger the SA:V of that cell
increases
decreases
does not change
changes proportionately
The _______________ grows faster than the _________________ when a cell grows
surface area , volume
cytoplasm , membrane
membrane , cytoplasm
volume , surface area
Objects can increase their SA:V by...
shrinking
creating more volume
growing larger
having a long, flat shape
Multicellular organisms overcome the problem of SA:V by
shrinking as they get older
growing really large
dividing into many cells
having many small cells that all have a different role, but work together to allow function
Why are cells microscopic in size?
they need to be able to hide
they need to maximise their SA:V to ensure they are efficiently supplied with nutrients so they can survive
they want to minimise their surface area
they need to minimise their SA:V to ensure they are efficiently supplied with nutrients so they can survive
Small cells have a...
Higher SA:V ratio
Smaller SA:V ratio
If a cell increases its SA:V ratio....
substances will enter and exit the cell more efficiently
substances will enter and exit the cell less efficiently
substances will not enter and exit the cell
no change will occur
