- in, this is called osmosis. it is a form of passive transport driven by the higher solute concentration inside the cell than outside. it requires no energy to run.
- out, this is called reverse osmosis. it is a form of active transport driven by higher pressure inside the cell than outside. it requires energy to create and maintain the pressure difference. living cells do not use this, instead they use a form of active transport involving pore pumpsembedded in the membrane to remove excess water and other undesired chemicals from the cell.

When water diffuses in and out of a cell, it is called osmosis. Osmosis is the movement of water molecules across a selectively permeable membrane, from an area of higher water concentration to an area of lower water concentration.

∙ 14y agoOsmosis - is the diffusion of water across a semi-permeable membrane from an area of high water concentration (low solute concentration) to an area of low water concentration (high solute concentration).

'What is it called when water diffuses into a plant cell and builds up firm pressure?
tugor pressure
What is an example of molecules that diffuses out of a cell?
Water, sodium, potassium, glucose all diffuse in and out of the cell.
What is the process in which water diffuses through a cell?
The process through which water diffuses through a cell is called osmosis. Water moves from an area of low solute concentration to an area of high solute concentration, across a semi-permeable membrane, in order to equalize the solute concentrations on both sides of the membrane.
Osmosis can be defined as?
Osmosis is a type of passive transport that occurs when water diffuses through a cell membrane.
How do plant cells react when they are placed in an environment with lower water concentration than inside of the cell?
The cells of a plant change shape depending on the availability of water. The cells and plant take measures to reduce the amount of water loss through their stomata and conserve the water they currently have.
The water in a cell does what?
diffuses in and out of the cell
When water diffuses into a plant cell and builds up firm pressure that is called?
Turgor pressure. When the plant cell's central vacuole swells with water, the cell membrane pushes against the cell wall, creating this pressure that helps maintain cell shape and support the plant's structure.

What is it called when iodine diffuses out of a cell?
Osmosis
How do unicellular get water?
Water diffuses across their cell membranes
Why does a cell diffuse items into the cell?
The cell needs food and water so it diffuses it to maintain health.
When water diffuses into a plant cell and builds pressure?
tugor pressure
What is an example of molecules that diffuses out of a cell?
Water, sodium, potassium, glucose all diffuse in and out of the cell.
What happens to a cell in a hypertonic solution?
In a hypertonic solution, the concentration of solutes outside the cell is higher than inside. This causes water to move out of the cell, leading to shrinkage or plasmolysis. The cell may become dehydrated and lose its normal shape.
What is a type of passive transport that occurs when water diffuses through a cell membranes?
osmosis
What is it called when water diffuses across a membrane?
osmosis i think
What would happen if a cell placed in a hypotonic solution?
When a cell is placed in a Hypotonic solution, the water diffuses into the cell, causing the cell to swell and possibly explode.
