What moves into and out of a cell through osmosis?
Osmosis is responsible for the passage of water across the membrane. Simply put osmosis means that water will travel from and area where there is more water (e.g. outside a ce…ll) to an area where there is less water (e.g. inside the cell). There are a few types of diffusion: 1. Simple diffusion: Small molecules such as O2 and ethanol can pass across membranes easily. 2. Facilitated diffusion: Some molecules bind to a membrane bound protein which carries them across the membrane. 3. Active Transport: This occurs when a molecules bonds to a a membrane bound pump which requires energy (ATP) to bring the molecules across the membrane.
1. It enters through the cell wall. 2. It enters through the cell membrane. (Note that it enters through the cell wall's pores; and the cell membrane has to be semi-permea…ble) 3. Since water in the plant cell is stored in the vacuoles, the water enters the vacuole. There, the cell has gained more water. (When the cell releases water, it is the same sequence of steps except BACKWARDS) Hope my Answer helped -Rin Rin
water because it moves
Yes. But only through a permeable or semi permeable membrane EDIT: The cell membrane is not itself permeable to water. However there does exist a type of protein pore called… an aquaporin in the membrane that can allow water to pass through, driven by diffusion or osmosis.
Through semipermeable membarane.
Water molecules move with the help of membrane proteins called aquaporins, which regulate the movement of water in an out of the cell. Because of the dual nature of the membra…ne (hydrophobic and hydrophilic), water doesn't simply diffuse in an out, although a certain percentage can slip in between phospholipids.
Water, from high to low concentration.
Osmosis is the diffusion of a solvent (usually water molecules) through a semipermeable membrane from an area of low solute concentration to an area of high solute concentrati…on, or conversely from an area of higher water potential to an area of lower water potential. Water will tend to flow from a hypotonic solution (low concentration of dissolved substances) into a hypertonic solution (higher concentration of dissolved substances). Water will in essence push or thrust (Greek osmos, push,thrust) from a place of low concentration of water to that of a high concentration of water as it requires it. The membrane allows only water and some select substances to pass through.
I believe red blood cells go through diffusion...just type this question into google: how do red blood cells use diffusion? and you should get some quality answers. hope this …helps!
Some water just "leaks" through the membrane. But most cells have Aquaporins in their membrane to allow the water to pass through more rapidly.
i am not sure, but i put false and i put proteins to correct it
No. Osmosis refers to the movement of the solvent (water) not the solute (potassium). The potassium is moved using cellular energy by an 'ion pump' process.
