Photosynthesis Photosynthesis removesremoves CO CO22 from the from the atmosphere and Cellular Respiration puts atmosphere and Cellular Respiration puts it it backback..

Photosynthesis releases Photosynthesis releases oxygenoxygen and and Cellular Respiration uses that oxygen to Cellular Respiration uses that oxygen to release energy from release energy from foodfood..

DiffusionDiffusion

Molecules of a substance move from Molecules of a substance move from areas of higher concentration to areas of areas of higher concentration to areas of lower concentration. This process will lower concentration. This process will continue until equilibrium is reached. No continue until equilibrium is reached. No energy is required by the cell. energy is required by the cell.

OsmosisOsmosis

Diffusion of water through a selectively Diffusion of water through a selectively permeable membrane. permeable membrane.

Facilitated DiffusionFacilitated Diffusion

The process that helps large molecules The process that helps large molecules pass through the membrane. Protein pass through the membrane. Protein molecules act as channels for large molecules act as channels for large molecules to pass from one side of the molecules to pass from one side of the membrane to the other side. No energy is membrane to the other side. No energy is required by the cell. required by the cell.

Active TransportActive Transport

Energy is required to transport materials Energy is required to transport materials across the cell membrane. Movement of across the cell membrane. Movement of molecules is against the concentration molecules is against the concentration differences. differences.
