Simple answer: Diffusion There are multiple methods: simple diffusion is where smaller molecules are able to pass into the cell based on the concentration of the substance on one side of the cell. Facilitated diffusion also relies on concentration but is aided through non-energy using processes, such as channels that are the correct physical shape and charge to draw in a molecule. Finally there is active diffusion, which requires an input of energy and usually works against a concentration barrier. Diffusion involving only the movement of water is known as osmosis.

When the concentration of solutes outside the cell and inside the cell are in equilibrium the solution is said to be?
When a cell is in a solution that has the same concentration of water and solutes, it is considered isotonic. Water still moves through the plasma membrane, but water enters and leaves the cell at an equal rate-it has reached an equilibrium, and there is no net movement of water.
How does hypertonic affect an animal cell?
hypertonic affects the animal cell by having a higher concentration of solutes than in the cell causing it to shink; which is called plasmolysis
What is the movement of across the cell membrane using cell energy?
This type of movement is called simple diffusion.
Why is a cell membrane called permeable?
because oil based fluids can get through it.
What do you called the movement of the blood as it carries food and oxygen to the cell body?
The movement of the blood is called circulation.
What is it called when the concentration of solutes is greater outside the cell the inside?
A hypertonic environment with regard to the cell.
What effect would non-permeating solutes have on osmosis and hemolysis?
It depends on where the non-permeating solutes were and what type of solution the cell is in. if non-permeating solutes were in the cell and their number was greater than the total number of solutes outside the cell, water would come into the cell and it would lyse. If there were a greater number of solutes on the outside of the cell, water would draw out of the cell and the cell would shrink. However, with time the solutes on the outside of the cell would diffuse into the cell and that could draw water with them.
Is the movement of water to try to balance concentrations?
Osmosis, which is the movement of water across a semi-permeable membrane from where it is in high concentration to where it is in lower concentration. The purpose of osmosis is to equalize the concentration of solutes inside a cell and outside a cell.
What is the movement of gases in and out of a cell called?
When a gas moves in and out of a cell it is called diffusion.
What osmosis in a cell?
For hypotonic solution, it means that the solution has lower concentration of solutes (salt, sugar etc) than inside the cell. If it is an animal cell, water will move from the hypotonic solution to inside the cell and the cell will swell and burst open. This is called cytolysis. For the plant cell, water will enter the cell and the cell wall enables the plant cell to swell and become turgid without bursting. For hypertonic solution, it's actually the opposite of hypotonic solution.It actually means that the solution has higher concentration of solutes than inside the cell. For the animal cell, water leaves the cell through osmosis and it will shrink and tiny spikes appear on the cell membrane. This is called crenation. For the plant cell, its cytoplasm shrinks away from the cell wall. This is called plasmolysis. Last but not least, the isotonic solution! This means that the concentration of solutes in the solution is equal to the conc of solutes inside the cell. The result: water moves equally in both direction and cell remains the same size. That's called dynamic equilibrium!

What is the movement of water in and out of the cell called?
The movement in and out of a cell is called active transport. Liquids inside cells contain different substances and there is movement in and out to maintain a proper balance of ions and molecules.
What do you called the movement of the blood as it carries food and oxygen to the cell body?
The movement of the blood is called circulation.
Concentration of solutes inside the cell equals outside the cell?
isotonic solution
