Ribosomes - RNA based "organelle" that strings together amino acids, Chloroplast - absorbs & transfers energy from photons to the bonds of sugar , Mitochondria - breaks down glucose and transfers electron energy into ATP, Cholesterol - Functions to maintain the stability & fluidity of the cell membrane, ER --> Golgi --> Vesicle --> Exocytosis - movement of synthesized protein , Separate Prokaryotes --> Engulfing --> Symbiotic Relationship --> Organelle formation - Process of endosymbiosis, Unsaturated Fatty Acids - Fatty acid tails that contain double bonds between carbons, resulting in kinks & "loose" packing, Saturated Fatty Acids - Fatty acid tails that contain only single bonds between carbons, resulting in "tight" packing, Hypotonic - Area where solute concentration is LOWER; water LEAVES this area, Hypertonic - Area where solute concentration is HIGHER; water MOVES TO this area, Passive Transport - Movement from high to low concentration with gradient; diffusion may be simple or facilitated , Active Transport - Movement from low to high concentration against gradient, Osmosis - Diffusion of water from high to low concentration, Into the cell - A cell is in an open beaker that has a solute potential of 1.3 and the cell has a water potential of 0.5. Where will water move?  , Out of the cell - A cell is in a system with a water potential of 1.0. The cell has a pressure potential of 2.3 and a solute potential of -1. Where will water move? ,
