Cellular Processes

Passive Transport the movement of materials through a cell membrane without using energy

2 Types of Passive Transport Diffusion Process by which food molecules, oxygen, water and other materials enter and leave the cell through the cell membrane Substances move from areas of higher concentration to areas of lesser concentration Osmosis Diffusion of water molecules through a selectively permeable membrane

Active Transport the movement of materials through a cell membrane using energy

Metabolism All controlled activities by which cells make/store and use energy

Mitosis Process by which body cells reproduce

Photosynthesis Process by which green plants use carbon dioxide, water, light energy to make glucose (sugar/energy/food) and oxygen Chlorophyll traps light energy Would this occur in autotrophs or heterotrophs?

Respiration Process by which the cell releases energy from food Would this occur in autotrophs or heterotrophs?

Fermentation Process that provides energy for cells without oxygen
