How diffusion and osmosis limit the size of a cell?
becauuse it does
How could cell wall determine the size and the shape of the plant cell?
The elasticity of cell wall determines the size and shape of the plant cell. A new cell stretches to the extent it is allowed by the cell wall.
Which is a factor that determines wether a molecule can cross the cell membrane?
Polarity
What two things limit the size of a cell?
2 things: Surface Area and Volume Surface: how much surface area (on the plasma membrane) determines how much nutrients the cell obtains, thus controlling how much the cell can grow. Volume: as the cell grows, the volume increases, and the cell's function stability decreases, thus weakening the cell and hindering the cells growth.
What single characteristic of the semipermeable membrane used in the laboratory determines the substances that can pass through them?
The size of the membrane pores determines which molecules can pass through.
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
Is it the size of cells or the number of cells that determines the size of an animal?
Cell number and cell size both determine the size of an animal.
A cell grows in size until it reaches what?
Their size limit
Does the cytoskeleton limit cell size?
No it doesn't.
Why are all large organsims including you multicellular?
Not quite true (colonies of bacteria can be quite large) but the upper limit of cell size is a speck that you can just barely see.
How do diffusion and osmosis limit the size of a cell?
becauuse it does

What are the limits to cell size?
There is a lower size limit to a cell because a cell has to be able to fit all of the cell parts in. There is an upper cell size limit because if the cell was too big, it would lose its cell membrane integrity.
How could cell wall determine the size and the shape of the plant cell?
The elasticity of cell wall determines the size and shape of the plant cell. A new cell stretches to the extent it is allowed by the cell wall.
Why cell transport and cellular communicator factor that limit cell size?
The cellular transport and cellular communication factor that limit the cell size because all the materials that go in and out of a cell must pass through the plasma membrane.
Why does a cell have a limit to a size?
To have better control of nucleus on over all activities of the cell.
Which is a factor that determines wether a molecule can cross the cell membrane?
Polarity
