The quiz below is designed to help test how much you understood about cell transport and energy. food; energy; oxygen; water; 2. 1. 1. Cell Transport To keep cells functioning normally cells need to move particles in and out of the cell. the process by which a substance is released from the cell through a vesicle that transports the substance to the cell surface and then fuses with the membrane to let the substance out. What is the function of a ribosome? Active Transport. The cell membrane is selectively permeable, which means... answer choices. Why do the phosphate heads face outwards? It is a thick solution that fills each cell and is enclosed by the cell membrane. transport that does not require energy (ATP_, a molecule dissolved in a solvent (Ex. This quiz is designed to show if you understand and can distinguish between the different types of cell transport. the contraction or shrinking of the cell membrane of a plant cell in a hypertonic solution in response to the loss of water by osmosis.
