This is also why you get thirsty after eating something salty.</p></li><li><p>Effects of Osmosis</p></li><li><p>Isotonic SolutionIf the concentration of solute (salt) is equal on both sides, the water will move back in forth but it won't have any result on the overall amount of water on either side.</p><p>"ISO" means the same</p></li><li><p>Hypotonic SolutionThe word "HYPO" means less, in this case there are less solute (salt) molecules outside the cell, since salt sucks, water will move into the cell.</p><p>The cell will gain water and grow larger. In plant cells, the central vacuoles will fill and the plant becomes stiff and rigid, the cell wall keeps the plant from bursting</p></li><li><p>Hypertonic SolutionThe word "HYPER" means more, in this case there are more solute (salt) molecules outside the cell, which causes the water to be sucked in that direction.In plant cells, the central vacuole loses water and the cells shrink, causing wilting.In animal cells, the cells also shrink.In both cases, the cell may die.</p></li><li><p>Active TransportMovement through a membrane that requires energy</p></li><li><p>Photosynthesis</p></li><li><p>AUTOTROPHSLiving things depend on energy to exist.Organisms that make the own food are autotrophsPlants and some other types of organisms are able to use the light energy from the sun to produce food. </p></li><li><p>PhotosynethesisThe process that coverts inorganic substances, CO2 and H2O, using the suns energy into an organic substance called glucose, C6H12O6 and a waste product,O2.</p></li><li><p>Chlorophyll plants principal pigment that absorbs sunlight </p></li><li><p>PHOTOSYNTHESISEQUATION </p></li><li><p>FACTORS THAT EFFECT PHOTOSYNTHESISAMOUNT OF WATERTEMPERATUREINTENISTY OF LIGHT</p></li><li><p>CELLULAR RESPIRATION</p></li><li><p>Cellular RespirationDefine cellular respiration A process that releases energy by breaking down food molecules in the presence of oxygenPlants make their own food (photosynthesis) and animals (heterotroph) must obtain their own food.Both plant and animal cells must undergo cellular respirationProcess occurs in the mitochondria</p></li><li><p>Chemical Equation for Cellular RespirationThe equation is the opposite of photosynthesis.</p></li><li><p>CHEMICAL ENERGY AND ATPThe activities of the cell are powered by chemical fuels.
