What cell part allows only certain substances to difuse into and out of the cell?
The cell's membrane allows only certain substances to diffuse in and out of the cell.
What substances easily diffuse a class of cell membrane?
sperm
Why is it important that a cell membrane does not allow all dissolved substances to diffuse freely through it?
magnets
What is the process of taking material into a cell?
There are a huge number of ways that this can occur. Water can simply diffuse through the cell membrane through osmosis, while other substances diffuse through special channels in the cell membrane. Some substances have to be brought into the cell through active transport, which requires the use of ATP.
How is an electolytic cell different from a galvantic cell?
electrons flow in the opposite direction
What part allows only certain subsTances to diffuse into and out of the cell?
The cell part that allows only certain substances to diffuse into and out of the cell is called the semi permeable membrane. This allows good substances to enter the cell.
What cell part allows only certain substances to difuse into and out of the cell?
The cell's membrane allows only certain substances to diffuse in and out of the cell.
What substances easily diffuse a class of cell membrane?
sperm
What substance will diffuse through a membrane?
The three substances that can diffuse through a cell membrane are CO2, O2, AND H2O.
Why is it important that a cell membrane does not allow all dissolved substances to diffuse freely through it?
magnets
Can oxygen diffuse across a cell membrane?
Yes, how else would our cells obtain oxygen?
What best describes the general direction of diffusion across the membrane of this cell?
Carbon dioxide would diffuse out of the cell
What substances diffuse into and what diffusen out of cells?
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.

What are 2 substances that diffuse freely across a cell membrane?
CO2, H2O, and O2 can all diffuse across a cell membrane. Also, small polar molecules (uncharged) and hydrocarbons easily diffuse across.
When substances move through a cell membrane by diffusion the cell uses a lot of energy to move those substances. Is this true or false?
a cell can only diffuse water, right? so it must be false cause that requires no energy
How is a electrolytic cell different from galvanic cell?
Electrons flow in the opposite direction.
