Apical epithelial cell structures functions in the movement of materials across the surface of the cell?
cilia
Why can a cell get only so large?
There is a surface area to volume ratio, as a cell gets larger it becomes harder and harder to transport materials inand out of the cell. There has to be enough surface area to supply the cell with all of the materials that it needs for survival.
A vacuole carrying waste materials from a cell fuses with the inside surface of the cell's plasma membrane the waste materials are then released to the medium outside of the cell?
exocytosis. :)
Why is surface area an important factor in limiting factor in limiting cell growth?
The materials entering or leaving a cell need to pass through the cell surface.
Which cell organelle sweep material across a surface?
Cilia

True or False The smaller a cell is the more difficult it is for the cell to move enough materials across its cell membrane?
False. A smaller cell has a higher ratio of surface area to volume, making moving the amount of required nutrients simpler.
How does the cell transport materials across the cell membrane?
a cell transports things across the cell membrane from areas of high concentration to ares of low concentration
How does the movement of materials across the cell membrane relate to an organism's survival?
A cell has to have some thing moving across it or the cell will most certanly die.
What would happen to a cell if materials could not move across the cell membranes?
it will died
What would happen to a cell if materials could not move across the cell membrane?
it will died

What 2 materials move across the cell membrane?
waste and nutrients
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
The process of moving materials across the cell membrane without the expenditure of energy is called passive transfer
