 * Directions**:
 * Under the heading assigned to your group, answer the following:
 * 1) =What is it? Definition=
 * 2) =How does it affect plant wilting?=
 * 3) =What are some examples of it?=


 * Click EDIT above and type (or copy and paste) information into the appropriate place
 * Each heading should have at least 3 additions (for example: one description in your own words, one real-life example, and one link to an additional resource)

Osmosis

 * **Osmosis** is the movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, aiming to equalize the solute concentrations on the two sides.(mf)

Vacuole

 * Vacuole-is a membrane-bound vesicle in the vesicle found in the cytoplasm of a cell whose function includes intracellular secretion, excretion, storage, and digestion.(et hg)
 * Vacuole wilts the plant because when a plant is dehydrated it uses its vacuoles as a source of water. Some of the stored water must exit the vacuoles so it can be used. When the vacuoles are drained they shrink and they do not push outward on the cell wall anymore. The lack of turgor pressure causes the plant to wilt.(et)
 * Examples: Plasmolysis in Elodia plant cells(et ce)

Balance (Equilibrium)

 * It can be used in two different ways as a noun and as a verd. noun: Equal distribution of weight verd: Balance is to make somethng even in weight, size, or amount.

Compartments (of living things)
it is a part or space marked or partitioned off of a cell (JL)
 * what it is?
 * It effects a plant wilting because

Cell

 * plants cells are cells that are in plants. plants cells are like animal cells but they have a cell wall and chloroplast.(aa)
 * the cell is the basic structral and fuctional unit of all known living organisms.(vr)

Permeability
the permeability of plant cell walls to macromolecules may limit the ability of enzymes to alter the biochemical and physical properties of the wall. Proteins of molecular weight up to 60,000 can permeate a substantial portion of the cell wall. Measurements of wall permeability in which cells are exposed to hypertonic solutions of macromolecules may seriously underestimate wall permeability. > **Osmosis** is the movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, aiming to equalize the solute concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves, without input of energy across a semipermeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations. Although osmosis does not require input of energy, it does use kinetic energy and can be made to do work, > water stress affects the quality of the yield, such as flowers, vegetables and fruits.
 * what is it?
 * how does it affect plant wilting?
 * Irrigation, applying water to assure sufficient soil moisture is available for good plant growth, as practiced in North Dakota is called "supplemental irrigation" because it is used to augment the rainfall that occurs during the growing season. Irrigation is used on full season agronomic crops to provide a dependable yield every year. It is also used on crops where
 * what are some examples of it?

=Membrane= > Memberane that acts as a selective barrier within or around the cell
 * What Is it ?

> The water potential of the envirment immediatley extenal to the cells is thus the critical factor determing wheather plants will wilt.
 * How does it affect plant wilting ?
