When plant cells absorb water the volume capacity in the vacuole and cytoplasm try to expand outwards with increased pressure . When the cytoplasm pushes against the cell wall, the wall resists the expansion in its rigid structure . As a result the pressure inside the cell increases, because the volume cannot increase. A cell in this condition is called a swollen turgid cell.
As the pressure inside the cell increases, water is pushed out of the cell to maintain the concentration of the sap. Eventually a balance is reached between the force drawing water into the cell and the force pushing water out of the cell, and the cell reaches equilibrium for osmosis.Excess water also transpires through the epidermis of the leaf ,stem or root.
This is called PLASMOLYSIS and it happens if a cell is placed in a hypertonic solution causing water to move out of the cell by osmosis. The cell is then said to be flaccid.
Flaccidity.
Or do you mean the osmosis/diffusion?
It will cause pressure a stiffen up the plant.
The term used to describe the shrinking of the plant cells when the cell membrane pulls away from the cell wall due to evaporation is called "plasmolysis".
Flaccidity,.
Plasmolysis
plasmolysis
the cell membrane. It is a protein mosaic this is hydrophobic on both sides and hydrophllic in the center.
Some cells have glycocalyces and this then would be the outermost part of the cell for them but all cells must have a plasma membrane and therefore I think this would be the best answer to the question.
The outer layer of a cell is the cell membrane or plasma membrane
The thin layer covering the outside of cells is called the cell membrane or plasma membrane. The cell membrane is a vital component of all cells, whether they are prokaryotic (lacking a nucleus) or eukaryotic (containing a nucleus). It serves as a selective barrier that separates the internal environment of the cell from the external environment, controlling the passage of substances in and out of the cell. The cell membrane is primarily composed of lipids (such as phospholipids), proteins, and carbohydrates. The phospholipid bilayer forms the basic structural framework of the membrane, with proteins embedded within or attached to the surface. These proteins play various roles, including transport of molecules, cell signaling, and maintaining the structural integrity of the membrane. Overall, the cell membrane is crucial for maintaining cellular homeostasis and allowing cells to interact with their surroundings while protecting their internal components.

plasmolysis
It is called plasmolysis. The cytoplasm and vacuole shrink but cell wall remains the same.

They help control what enters and leaves the cells.
They help control what enters and leaves the cells.
The cell membrane has one function in all cells. It controls what enters and leaves the cell and helps to regulate transport between cells.
Cell membrane
Membrane compartments in eukaryotic cells are organelles.
It controls what enters or leaves the cell
The membrane-covered compartment of eukaryotic cells are called vesicles. The vesicles are developed when a part of the membrane nips off.
When cell is placed in a hypertonic solution water moves out, first from cytoplasm and then from vacuole. Cell membrane shrinks away from the cell wall. This is known as plasmolysis. Plasmolysis is when a protoplast of a plant cell starts to shrink due to water loss from the cell. This causes gaps between the cell wall and cell membrane.
It's the cell membrane that controls when enters and leaves a cell.
