What is the difference between passive versus active transport?What type of transport is osmosis? (3 points) Passive transport: Active transport: Osmosis:

<p> Passive transport and active transport are two ways that substances can get across cell membranes:<br />1. Passive transport is the movement of substances across a cell membrane without the use of energy by the cell. Substances move along the concentration gradient, from an area with high concentration to an area with low concentration.<br />2. Active transport on the other hand, is the movement of substances across a cell membrane that requires energy because substances move against their concentration gradient, that is, from an area of low concentration to one of high concentration.<br />3. Osmosis is a type of passive transport. Osmosis refers to the movement of water molecules across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. It happens so as to equalize concentrations across the membrane.</p>
