Everything moves from cell to cell through the membrane, either through active transport (cell uses energy to move materials from areas of low concentration to areas of high concentration) or diffusion (cells passively transfer materials from areas of high concentration to areas of low concentration, which is natural and thus requires no energy)

What kinds of molecules pass through a cell membrane most easily?
small and hyrdophobic molecules
What kind of molecules can easily pass through a cell membrane?
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).
What is meant by cell membrane is semipermeable?
It allows only certain molecules to pass through.
Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
What is the thin layer around the cell that acts like a gate for the cell?
The cell wall. This structure is made up of a phospholipid bilayer and is studded with transport proteins that help pump molecules in and out of the cell. Many molecules are small enough to pass through the cell wall unaided by these proteins.
How do small molecules get through the cell membrane against a concentration?
How do small molecules get through a cell membrane
What goes through the cell membrane?
Nonpolar molecules (example: lipids) Small polar molecules such as water
What part of the cell membrane allows small molecules to pass through?
the cell membrane

In general the net movement of small uncharged atoms and molecules through the membrane of a cell will occur until?
Molecules will move into or out of the cell until it becomes isotonic to its surroundings. This means that the concentration of the molecules inside the cell is equal to the concentration of the molecules outside the cell.
What types of materials can enter the cell?
small molecules through the integral proteins in the phospholipid bilayer
What is the meaning of selectively permable?
Selectively permeable means that only certain objects can pass through. I've encountered that phrase in cell Biology, when talking about cell membranes. The cell membrane is made of phospholipids that only allow certain substances through. Water can pass through because the molecules are small enough to pass through small holes in the membrane. Other molecules, such as sodium or potassium, can be transported using protiens.
What kind of substance cannot pass through the cell membrane?
lipids, and ribosomeslipids
What types of molecules diffuse through the cell membranes by facilitated diffusion?
molecules that can survive the hydrophobic interior of the lipid bilayer
What is large molecules to small molecules called?
cell wall
