What cell main job is to control which substances enter and leave a plant cell.?
The cell organelle responsible for controlling which substances enter and leave a plant cell is the cell membrane, specifically the plasma membrane. The plasma membrane is a selectively permeable barrier composed of phospholipids and proteins that regulate the passage of molecules such as nutrients, water, and waste products. Through processes like diffusion, osmosis, and active transport, the plasma membrane maintains cellular homeostasis by allowing essential substances to enter the cell while preventing harmful substances from entering.
What is deplasmolysis?
When a plant cell is placed in a hypotonic solution then plant cell gains water by osmosis there is swelling of the contents of the cell away from the cell wall ,this phenomenon is known as deplasmolyzis
Is cell wall an impermeable membrane?
No, the cell wall is easily permeable and allows most substances to enter or leave without any resistance
In what plant cell structure is water stored?
Water is stored in the vacuole of a plant cell.
When a plant cell is placed in a hypotonic solution the cell wall prevents?
The plant cell wall helps prevent bursting. When placed in a hypotonic solution, water will enter the cell, because the concentration of solutes inside the cell is greater than outside. The cell wall helps to support the cell, and maintain rigidity.
What process cause the water to enter or leave the cell?
the process that causes the water to enter and leave the cell is diffusion
When a person is dehydrated does water enter or leave the cell?
The water leaves the cell.
What in a plant cell lets things enter and leave the nucleus?
The nuclear membrane.
What is the function of the cell membrane in a plant cell called?
The cell membrane protects the cell and regulates what substances enter and leave the cell.
What controls substances that enter and leave the cell?
IT depends on what cell. In the plant cell it is the cell wall and the cell membrane. But in the animal cell it is only the cell membrane.

What part of a cell allows food and water to enter and waste to leave?
vaclouse
What is the effect when you pour salt on a plant?
If the plant is not a salt water plant, then plasmolysis will occur when you pour salt on a plant.When you pour salt on a plant water molecules inside the cell are drawn out. When the water molecules leave the cell, the cell becomes dehydrates and shrinks. This is called plasmolysis.
What will happen to a freshwater bacterial cell that is placed in salt water Will water enter or leave the cell?
If a freshwater bacterial cell is placed in salt water, water will leave the cell due to the higher concentration of solutes in the surrounding salt water. This process is known as plasmolysis, and it can lead to the bacterial cell shriveling up and potentially dying due to dehydration.
What substance enters and leaves a plant cell through the process of osmosis?
Water enters and leaves a plant cell through the process of osmosis. When the concentration of water inside the cell is higher than outside, water will move into the cell, and when the concentration is higher outside, water will leave the cell.
Why would some nutrients leave the plant cell when it becomes wilted from being Soaked in sat then fresh water?
When a plant cell becomes wilted from being soaked in saltwater, it loses water through osmosis due to the higher concentration of salts outside the cell. This loss of water can cause nutrients to be expelled from the cell along with the excess water, reducing the overall nutrient content of the cell. When the wilted plant cell is then transferred to fresh water, water rushes back into the cell through osmosis, but the lost nutrients may not be able to re-enter the cell as easily, leading to a nutrient loss.
What does osmosis do to plant and animal cells in pure water?
Plant cells have a strong rigid cell wall on the outside of the cell membrane. This stops the cell bursting when it absorbs water by osmosis. The increase in pressure makes the cell rigid. This is useful as plants do not have a skeleton. Instead the leaves and shoots can be supported by the pressure of water in their cells. If plant cells lose too much water by osmosis they become less rigid and eventually the cell membrane shrinks away from the cell wall.
