why can’t cells be infinitely large? (cell size limitation #1)
getting materials into cells at an efficient rate (nutrients, water, oxygen)
why can’t cells be infinitely large? (cell size limitation #2)
removing things from cell quickly (waste)
why can’t cells be infinitely large? (cell size limitation #3)
DNA limits cell size (if cell is too big then DNA cannot make enough proteins to support it)
lower limits to cell size (minimum value)
a cell must be large enough to house the required material (DNA and proteins) to survive and reproduce
upper limits to cell size (maximum value)
limited by the amount of surface needed to obtain nutrients and dispose of waste
why can’t cells be large? (simple term for dummies (me))
if cells were too big, diffusion would take an extremely long time and a cell could die from starvation or poison itself with its wastes
surface area to volume
how much space is on the outside (cell membrane) compared to the space on the inside of the cell
surface area to volume ratio
as the surface area INCREASES, its volume INCREASES FASTER
what is surface area on a cell and what is the formula?
the cell membrane (the outside) and L*W*# of sides
what is volume on a cell and what is the formula?
the space inside the cell and L*W*H
