Osmosis

 * **__Osmosis__** is The Passage Of Water From a Region Of High Water Concentration Through A Semi-Permeable Membrane To Semi-Permeable Membrane To a Region Of Low Water Concentration. ( A.V ]
 * **__Example :__** It Has Been Estimated That An Amount Of Water Equivalent To Roughly 250 Times The Volume Of The Cell Diffuses Across The Red Blood Cell Membrane //Every Second//; The Cell Doesn't Lose Or Gain Water Because Equal Amounts Go In And Out. ( M.R & D.M ]
 * __**Effect**:__ Plant cells are enclosed by a rigid cell wall. When the plant cell is placed in a hypotonic solution, it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is said to have become **"turgid"** i.e. swollen and hard. The pressure inside the cell rises until this internal pressure is equal to the pressure outside. This liquid or hydrostatic pressure called the turgor pressure prevents further net intake of water. ( Group 3 ]

Vacuole

 * What is it? The vacuole is a membrane boundorganelle which is present in all plants and fungal cells and some protist, animal and bacterial cells.
 * How does it affect plant wilting? As you can imagine, when the vacuoles are drained, they shrink and thus do not push outward on the cell wall anymore. This lack of turgor pressure causes the plant to wilt. what are some examples of vacuole?The salt will draw some of the water out of the fruit.

Balance (Equilibrium)

 * plant cells require a hypotonic enviroment (which keeps cell walls from leening)

Compartments (of living things)
What is it? How does it effect plant wilting? Examples of compartments.
 * The compartmen is a specialized subunit within a cell that has a specific function and is usually separately enclosed with its own lipid bilayer. They are found in both animal and plant cells.
 * The vacuole which is the storage compartment of water begins to shrivel up when it doesn’t have water. This causes the plant to become dehydrated. Then the plant begins to die and starts to wilt.

 * Mitochondria
 * Cell Wall
 * Plasma Membrane
 * Vacuole

Cell
Cells are made of atoms The cell is one of the most basic units of life. And there cells that only function when part of a large organism. Like a living thing cells die. one of the major difference in cells occurs between plants and animals (gd)(ym)

Permeability

 * Permeability is something that can be passed through somethig
 * it is not allowing water to go through the plant
 * examples are cloth and sand

Membrane

 * What is it: Definintion: The semipermeable membrane that encloses the cytoplasm of a cell. (ak)
 * How does it affect it: This occurs because the calcium and nitrate ions freely permeate the cell wall and encounter the selectively permeable plasma membrane. The space between the cell membrane and the cell wall enlarges and the plasma membrane and the protoplasm within it contract to the center of the cell. This happens because the dytoplasm extends to the cell wall, and the cells would die i f not transfered quickly enough. (ak)
 * Examples: A good example of a membrane is a room the door allows people to come in & out (bg)
