Document Summary

Isotonic: [solute] = [cell] , plant cell becomes flaccid bc no net movement with water. Hypotonic: [solute] < [cell] , plant cell becomes turgid because water moves into cell causing it to swell. Hypertonic: [solute] > [cell], plant cell will shrivel (plasmolyze) because water is moving out. Control group: stays the same throughout the experiment. Experimental group: what alterations will be made on. The fluid-mosaic model describes the plasma membrane of animal cells. The plasma membrane that surrounds these cells has two layers (a bilayer) of phospholipids. Tetracycline: antibiotic that acts by preventing bacterial protein synthesis. Penicillin: used to treat gram positive; works but inhibiting cross linking in the bacterial cell wall. Chloramphenicol: used for pink eye; inhibits bacterial protein synthesis. Gram positive: have one membrane and a thick layer of peptidoglycan which caused them to stain purple. Gram negative: have a thin layer of peptidoglycan between two membranes; stains pink.
