What type of compound would easily diffuse into the cell?
A hydrophobic molecules (such as a steroid molecule) can easily diffuse into the cell
When the concentration of free water molecules is higher outside a cell than inside the cell water will diffuse?
In this situation there will be endo-osmosis. The water molecules will diffuse from outside to inside cell.
Why do sugar molecules not diffuse through a plant cell membrane?
The membrane is semi-permeable. Sugar molecules are too large to diffuse through.
Can all molecules diffuse through all cell membranes?
No, there are specific cell membranes that allow only certain molecules to pass through. Some stay open and others must be opened ( like a gate ).
What large molecules need help getting across cell membrane?
In general, molecules that cannot diffuse across the cell membrane are either very large, such as starches and fats, or very polar.
Glucose is a molecule that can move across the cell membrane if the concentration of glucose is high or inside the cell than outside the cell then what will happen by the process of diffusion?
glucose molecules will diffuse out of the cell. apex

If the concentration of glucose is higher inside the cell than the cell then outside the cell then what will happen by the process of diffusion?
Water will move out of the cell. Glucose will not move into the cell without the help of a helper molecule. Glucose molecules will diffuse into the cell.(APEX)
Do molecules must always diffuse into a cell?
not if the concentration is equal inside and outside of the cell
The part of the cell that is in most direct contact with the environment is the?
The cell membrane, which surrounds the cell and is responsible for which molecules are allowed to diffuse into or out of the cell and which molecules are impermeable to the membrane
Do lipid soluble molecules diffuse into a cell more rapidly than water soluble molecules?
Yes.
What is an example of molecules that diffuses out of a cell?
Water, sodium, potassium, glucose all diffuse in and out of the cell.
What molecule is able to easily diffuse across the cell's membrane?
Carbon dioxide, oxygen and some nonpolar molecules diffuse easily.
Why do molecules easily diffuse across a cell membrane while glucose molecules do not?
Glucose is too big to pass throught.
What is the functions to the cell membrane?
The Cell membrane contains the insides of the cell. The membrane is also selectively permeable, allowing nonpolar molecules to simply diffuse into the cells, such as lipids, steroid based hormones, CO2, etc. It also allows small polar molecules to diffuse through, such as H2O.
