Final answer:Active transport involves energy expenditure to move substances against their concentration gradient and includes solute pumping, phagocytosis, and pinocytosis. Passive transport moves substances along the concentration gradient without energy use, and includes processes like osmosis and simple diffusion.Explanation:Membrane transport can be characterized by its active or passive nature. The phrases that apply to active transport include:b. explain solute pumping, phagocytosis, and pinocytosisd. may occur against concentration and/or electrical gradientse. use hydrostatic pressure or molecular energy as the driving forcef. move ions, amino acids, and some sugars across the plasma membraneThe phrases that apply to passive transport include:a. account for the movement of fats and respiratory gases through the plasma membranec. include osmosis, simple diffusion, and filtrationPassive transport includes mechanisms such asosmosis,simple diffusion, andfacilitated diffusion, where substances move along the concentration gradient without the expenditure of cellular energy. Active transport, on the other hand, involves the cell expending energy, often in the form of ATP, to move substances against their concentration gradient through processes such assolute pumping,phagocytosis, andpinocytosis....
