Bio cards quarter exam next week

QuestionAnswer
What is passive transport? Movement of molecules across a cell membrane without energy input which form a cell.
What is diffusion Movement of molecules,in a fluid.From HIGH concentration to LOW concentration.
Concentration Gradient Concentratrion of a substance to a location to another
What is osmosis Semipermeable membrane which form a area of higher water concentration to lower water concentration
What is Isotonic? If both sides have the same concentration of dissolved parcels as a cell
Hypertonic? Solution higher concentration of dissolved particles than a cell
Hypotonic? Solution with low concentration of dissolved particle in a cell
Facilitated Diffusion? diffusion(movement in molecules a fluid from high to low concentration)of molecules across a membrane through transportive proteins.
Active transport? Drives molecules across a membrane from a region of low concentration to region of high concentration(solute-which is sugar)
What is Endocytosis? process of taking liquids of fairly large molecules into a cell by engulfing them in membrane
Phagocytosis? Type of endocytosis in which cell membrane engulfs large particles.
Exocytosis? opposite of endocytosis releases the substance out of a cell by the fusion of a vesicle with the membrane
