How much water enters and leaves a cell?
As much as the plant needs. The excess water is thrown out.
How does a cell wall help plants?
It provides support for the plant cell. If the plant cell fills with water, the cell wall will prevent it from bursting, allowing the cell to reach a "turgid", or rigid state. This is contrary to animal cells, which have no cell wall and burst if too much water enters them
What vital substancce do plants obtain through their pores?
Openings in plant leaves are called stomata. They are the point that carbon dioxide enters the plant, and the point that oxygen and water leave the plant. In the roots, there are no pores. Ions and water are absorbed either directly through the cell wall (apoplast) and plasma membrane via diffusion, or substances are taken through the membrane by various transporter proteins.
How does excess water leave a plant?
xylem moves the water from the roots to the rest of the plant. on the underside of leaves there are tiny holes called 'stomata' and surrounding them are bands called 'guard cells.' the guard cells open and close the stomata and water and oxygen are released.
If water moves into a cell and the cells swells it's called what?
When a cell is placed in a hypotonic solution, water enters the cell through osmosis, and the cell swells.
Is water moving into the root cells of a plant an example of osmosis?
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-permeable) 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

When water leaves a plant cell the osmotic pressure will increase of decrease?
The osmotic pressure will decrease. The osmotic pressure is decreased because the water is leaving the cell.
What part of a plant cell the cell wall or the cell membrane what enters or leave the cell?
The cell membrane controls what enters or leaves the cell.
What happens when plant is put into water?
If a plant cell is placed in fresh water, there will be a net movement of water into the cell - because the solute concentration inside the cell is greater than outside. This occurs because the system is attempting to reach equilibrium (where the concentrations inside and outside are equal). Unlike an animal cell, a plant cell will not burst when excess water enters the cell. This is because the cell wall helps the plant cell maintain its structure.
What is the function of the secondary wall in the plant cell?
A major function of the cell wall is to act as a pressure vessel, preventing over-expansion when water enters the cell.

What is the role of water in maintaining the cell structure or turgidity of cell?
In plant cells water enters the cell through at least two methods, but the important part is when the water is in the cell, building up in volume and pressing against the inner cell wall. The cell wall, obeying the laws of physics, pushes back until the pressure is equalized. maintaining structure and turgid conditions within the cell.
What happens when excess water enters the plant cell?
If excess water moves into an animal cell, it will eventually burst. This happens if the cell is placed in a hypotonic solution (a solution with a lower solute concentration than the cell).
Cells in a plant root drink water through the cell membrane. what process is going on?
Osmosis (endo-osmosis to take water inside plant cell)

xylem moves the water from the roots to the rest of the plant. on the underside of leaves there are tiny holes called 'stomata' and surrounding them are bands called 'guard cells.' the guard cells open and close the stomata and water and oxygen are released.
