1

Autotroph

An organism capable of synthesizing its own food from inorganic substances using light or chemical energy. Green plants, algae, and certain bacteria are autotrophs.

2

Heterotroph

Organism that cannot make its own nutrients and must rely on other organisms for food.

3

Cellular Respiration

Is the process through which cells convert sugars into energy.

4

Pigment

A substance occurring in plant or animal tissue and producing a characteristic colour, such as chlorophyll in green plants

5

Chlorophyll

Any of a group of green pigments that capture light energy used as the energy source in photosynthesis and that are found in the chloroplasts of plants

6

Thylakoid membrane

Are membrane-bound compartments inside of the chloroplasts. Thylakoids are the epicenter for photosynthetic light-reactions.

7

ATP

Energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

8

Aerobic respiration

The process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy

9

Anaerobic respiration

Transfers energy from glucose to cells,occurs when oxygen is not present, and transfers large amounts of energy quickly

10

Glycolysis

Is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates.

11

Fermentation

Chemical process by which molecules such as glucose are broken down anaerobically.
