How do substance like co2 and water move in and out of the cell?

Carbon dioxide is a small nonpolar molecule which means that it can easily diffuse through the lipid bilayer of the cell membrane. Carbon dioxide moves from an area of high concentration to an area of low concentration. Diffusion is passive transport (no ATP required).
Water is a polar molecule but it is pretty small so it can still dissolve through the lipid bilayer into the cell. The movement of water from an area of lower solute concentration to an area of higher solute concentration across a semipermeable membrane is called osmosis. Aquaporins are small water channels embedded in the lipid bilayer. These protein water channels provide a hydrophilic (polar) tunnel through the lipid bilayer for the fast movement of water across the membrane.. Aquaporins are a form of facilitated diffusion (diffusion with "help"). Osmosis and facilitated diffusion are forms of passive transport.

∙ 9y agoAs the cell functions the concentration of Carbon Dioxide in the cell increases whereas the concentration of Carbon Dioxide in the external environment is low.Carbon Dioxide moves out of the cell from a region of higher concentration to the external environment which is the region of lower concentration.
Water moves in and out of the cell from a region of higher concentration through a semi-permeable membrane to a region of lower concentration by the process of osmosis, although water molecules would have to have a certain momentum to pass through the apolar middle region of the celular membrane. There are transporter proteins called acquaporins that allow water molecules to pass through, which are responsible for most of the water that passes through into and outside the cell.

A substance that moves across a cell membrane without using the cell's energy tends to move?
from an area of low concentration to an area of high concentration (if it is water) the opposite if it is a solid
What direction does water move when cells are placed in hypertonic solution?
Water moves out of the cell in hypertonic solution.
During osmosis which direction does the water move into the cell out of the cell or does it move in and put equally?
During osmosis water moves in and out of the cell equally in both directions.
What is cytoplasm's job in the cell?
The cytoplasm is a jelly-like substance composed of water, salt, and other organic molecules and is simply a medium for the organelles to move around in, just as the air we live in.
What happens when the concentration of dissolved substances is greater outside the cell than inside?
Particles always move from an area of high concentration to an area of low concentration. Therefore, if the concentration of dissolved substances is greater outside the cell, they will travel into the cell until there is an equal concentration of the substance on both sides of the cell wall.

How and when do cells let water in or out?
Cells let water in or out of there systems through a process called osmosis. Osmosis is the movement of water across a cell membrane from high concentration to low concentration. If there is a higher concentrations of solute ( a substance that isn't water ex. salt) in the cell, the water will move into the cell. The cell will eventually fill with water and burst If the is a higher concentration of water in the cell than in the enviroment, water will move out of the cell and the cell will eventually shrink and shrivel
How do substances like co2 and water move in and out of the cell?
By the process of diffusion and osmosis.
How do solutes get in and out of the cell?
By the processes such as diffusion, osmosis and active transport...
What direction does water move when cells are placed in hypertonic solution?
Water moves out of the cell in hypertonic solution.
What occurs when the plasma membrane surrounds a large substance inside the cell and move it outside the cell?
exocytosis
What substance easily travel across the cell membrane glucose molecules water molecules or sodium?
Of the three, water will move easily. The others require help and therefore the use of energy.
During osmosis which direction does the water move into the cell out of the cell or does it move in and put equally?
During osmosis water moves in and out of the cell equally in both directions.

How does cell maintain its diploid cell number?
water will move ouside of the cell
