Chapter 1:Photosynthesis and the carbon cycle, 1.1:Photosynthesis

the process where plants use light energy to make glucose

Photosynthesis

organisms that make their own food

Producers

the substances needed for photosynthesis

Carbon dioxide and water

the substances produced by photosynthesis

Glucose and oxygen

the energy source needed for photosynthesis

Light energy

the green pigment that absorbs light energy

Chlorophyll

the structures in plant cells where photosynthesis takes place

Chloroplasts

the sugar produced during photosynthesis

Glucose

the substance plants store excess glucose as

Starch

the amount of light energy falling onto an object

Light intensity

what usually happens to the rate of photosynthesis when light intensity increases

It increases

what happens when another factor becomes limiting

Increasing light intensity no longer increases the rate of photosynthesis

the gas produced during photosynthesis

Oxygen

the test for oxygen

A glowing splint relights

what can be counted to estimate the rate of photosynthesis in a water plant

The number of gas bubbles produced per minute

more bubbles per minute indicate what

A faster rate of photosynthesis

the reactants in photosynthesis

Carbon dioxide and water

the products of photosynthesis

Glucose and oxygen

the word equation for photosynthesis

Carbon dioxide + water → glucose + oxygen

the process that releases energy from glucose

Respiration

the word equation for respiration

Glucose + oxygen → carbon dioxide + water

what happens to energy during photosynthesis

Energy is stored in glucose

what happens to energy during respiration

Energy is released from glucose

which two processes do plants carry out

Photosynthesis and respiration

a substance used up in a chemical reaction

Reactant

a substance made in a chemical reaction
