Cellular Transportation
4. Choose the correct word to complete these terms and definitions (3 points each):
Active Transport: Movement of molecules across the cell membrane ____(with/without)____ the use of cellular energy.
Passive Transport: Movement of molecules across the cell membrane ____(with/without)____ the use of cellular energy.
Diffusion: A type of passive transport. It is the random movement of molecules from ____(lower/higher)____ concentration to ____(lower/higher)____ concentration.
Osmosis: A type of passive transport. It is the diffusion of ____(air/water)____molecules across a semi permeable membrane.
Semi Permeable Membrane: Allows some things to pass through, but not all. The cell membrane is semi permeable. For example, a mesh bag for carrying grapefruit. It allows water, air, and bugs in and out of the bag. But, it doesn't allow the grapefruit to pass through.
Homeostasis is reached when the conditions inside the cell match the conditions outside the cell.
