• The movement of water molecules from an area of high concentration to a low concentration across a permeable membrane.

• The movement of particles from an area of high concentration to a low concentration across a permeable membrane.

• The movement of particles from a area of high concentration to a low concentration until they are evenly distributed.

Multiple Choice

What is a similarity between osmosis and diffusion?

​ACTIVE TRANSPORT

Active transport is the movement of a substance from a lower concentration to a higher concentration across a semi-permeable membrane requiring energy from respiration.

​ACTIVE TRANSPORT

•Energy is required to absorb minerals or other substances against the concentration gradient.

•This process requires energy and carrier proteins in the cell membrane.

Multiple Choice

What is active transport?

• The movement of substances from a high concentration to a low concentration until evenly distributed.

• The movement of substances from a high concentration to a low concentration across a semi permeable membrane.

• The movement of substances from a low concentration to a high concentration which the help of energy.

Multiple Choice

What is a difference between osmosis and active transport?

• active transport requires energy while osmosis doesn't.

• active transport doesn't requires energy but osmosis requires energy.

• I am not too sure
