The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
No, the cell membrane controls what comes and goes out of the cell
Water can pass freely through the cell membrane.
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
During osmosis, water molecules move through the cell membrane by passing through microscopic openings in the membrane. The openings are large enough for the water molecules to pass through.
A cell membrane is in every plant and animal and it lets in water, nutrients, and food to the cell. The membrane MUST be permeable because then it wouldn't of let the in water, nutrients, and food into the cell. If the membrane was stiff, the molecules of water, nutrients, and food would not be able to fit into the cell.
small and hyrdophobic molecules
Small, Non-polar molecules. If the molecule is polar, it sticks to both sides of the membrane, and has to go through selective routes. The easiest to get through is the Non-polar (oxygen and carbon).
How do small molecules get through a cell membrane
Some molecules can't go through the cell membrane.
In a cell in the human body diffusion takes place in the cell membrane. The cell membrane allows smaller sized molecules to pass through.

Describe how water molecules move through the cell membrane during osmosis?
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.

The cell membrane only allows certain molecules through.
No they pass through the cell membrane. The cell membrane is selectively permeable to ions and organic molecules
