passive transport
|
|
a type of passive transport in cells in which molecules move from areas where there are more of them to areas where there are fewer of them
|
diffusion
|
|
occurs when molecules of one substance are spread evenly throughout another substance

the total of all chemical reaction in an organism
|
metabolism
|
|
process by which plants and many other producers use light energy to produce imple sugar from carbon dioxide and water and give off oxygen
|
photosynthesis
|
|
chemical reactions occur that break down food molecules into simpler substances and release their stored energy
|
cellular respiration
|
|
process by which oxygen lacking cells and some one-celled organisms release small amounts of energy from glucose molecules and produces wastes such as alcohol carbon dioxide & lactic acid
|
fermentation
