How does cell shape change during osmosis and cell diffusion?
Osmosis effects the volume of a cell. when the cell has equal water molecules in the water aroung it and in the cell it is shaped normally. When there is a lot of salt in the water the cell shrinks because there is less water content in the salty water thus the cell gets rid of the extra water molecules. When there is very little salt content in the water the cell gets bigger because the cell absorbs to much water.
Does the cytoskeleton limit cell size?
No it doesn't.
Why must complex muticellular organisms have transport systems?
Large organisms need transport systems to supply all their cells with food, oxygen and other materials.Multi-cellular organisms are too big and not all of their cells have contact with the external environment. All organisms need to exchange substances with their environment - take in needed molecules and get rid of waste. A uni-cellular organism can use the processes of osmosis, diffusion and active transport to transport substances in and out of the organism, which is in this case just one cell. But as organisms increase in size, they need a specialized transport system to exchange substances between the internal environment and the external environment. Interestingly enough, osmosis and diffusion are still the important mechanisms at the cellular level.
What makes the cell limited size?
The things that can limit a cells size are the surface to volume ratio, Diffusion and The amount of DNA Diffusion is a fast and efficient way for small particles to pass through The amount of DNA means that the bigger it is the more DNA it needs.
What is the effect of size of uptake on diffusion in agar?
larger the size, the smaller the surface area to volume ratio, hence the slower the rate of diffusion into the agar jelly :)
How does osmosis and diffusion limit the size of a cell?
diffusion and osmosis limit the size of a cell by how fast is can move
How diffusion and osmosis limit the size of a cell?
becauuse it does
What Word Goes in There As cell size goes effectiveness of diffusion and osmosis goes This drives the cells to stay small?
as a cell goes blank effectiveness of diffusion and osmosis goes bank.
What things limit cell size?
DNA, Diffusion, and Surface Area to Volume Ratio.
What 3 things limit cell size?
DNA, Diffusion, and Surface Area to Volume Ratio.
Does diffusion effect cell size?
Yes

Water spreading through a membrane with a change in cell size is an example of what?
Water molecules spreading through a membrane with a change in cell size is an example of osmosis. In osmosis fluid passes both in and out of the semipermeable membrane in osmosis, but usually there's a net flow in one direction.
A cell grows in size until it reaches what?
Their size limit
What doesn't occur as a cell grows larger in size?
Diffusion across the cell membrane is impaired
Does the cytoskeleton limit cell size?
No it doesn't.
