Photosynthesis, Photosynthesis

autotroph or producer

An organism that can make its own food

heterotroph or consumer

An organism that cannot make its own food.

reactants

The 'inputs' of a chemical reaction. Located on the left side of a chemical equation.

products

The 'outputs' of a chemical reaction. Located on the right side of a chemical equation.

xylem

Carries water and minerals through a plant.

phloem

Carries food (glucose) through a plant.

stomata

Small openings on the underside of a leaf through which oxygen and carbon dioxide can move. Where gas exchange occurs in a plant.

chloroplast

Location inside of a plant cell where the process of photosynthesis occurs.

chlorophyll

Pigment which 'fills' chloroplast. This pigment absorbs sunlight.

photosynthesis

A process plants use to turn sunlight into food.

oxygen

A gas that plants release ( PRODUCT) during photosynthesis

carbon dioxide

A gas that plants take in (REACTANT) through small holes in their leaves for the process of photosynthesis.

water, sunlight, carbon dioxide

3 main ingredients for photosynthesis (a.k.a. REACTANTS)

glucose

A simple sugar produced by plants and used as food.

roots

Absorbs water and minerals from the ground. Anchors plant in ground.

sunlight

Taken in by the leaves of the plant to give the chloroplasts energy for food production.

Stem

supporting structure of a plant that connects roots and leaves and carries water and nutrients between them

O2

oxygen molecule

CO2

carbon dioxide

C6H12O6

glucose, also known as sugar

Consumers (heterotrophs)

Incapable of photosynthesis and must obtain their energy by consuming other organisms

-ose

sugar, carbohydrate

Carbohydrates

The starches and sugars present in foods; your digestive system usually breaks them down into GLUCOSE.

light-dependent reactions

reactions of photosynthesis that use energy from light to produce ATP and NADPH

Light Independent Reactions (Calvin Cycle)

set of reactions in photosynthesis that do not require light; energy from ATP and NADPH is used to build high-energy compounds such as sugar; also called the Calvin cycle

ATP

(adenosine triphosphate) main energy source that cells use for most of their work

ADP

a lower-energy molecule that can be converted into ATP by the addition of a phosphate group

Thylakoid

A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.

Stroma

fluid portion of the chloroplast; outside of the thylakoids

Grana

stacks of thylakoids
