answer

Equation for the Chemical Reaction of Photosynthesis (words)
question

Equation for the Chemical Reaction of Photosynthesis
answer

Six molecules of carbon dioxide react with six molecules of water to form 1 molecule of glucose and six molecules of oxygen.
question

Photosynthesis
answer

The process of changing light energy to chemical energy.
question

Photosynthesis
answer

Occurs in plants and some algae .
question

Photosynthesis
answer

Plants need light energy, CO2, and H2O .
question

Photosynthesis
answer

Takes place in the chloroplasts, using chlorophyll.
question

Photosynthesis
answer

Plants capture light energy and use that energy to make glucose.
question

Photosynthesis
answer

Sunlight provides the energy needed by chlorophyll to change molecules of carbon dioxide and water into glucose.
question

Photosynthesis
answer

Oxygen is released in this reaction.
question

Photosynthesis
answer

Carbon dioxide enters the leaf through holes called stomata.
question

Photosynthesis
answer

CO2 combines with the stored energy in the chloroplasts through a chemical reaction to make glucose.
question

Photosynthesis
answer

The sugar is moved through tubes in the leaf to the roots, stems and fruits of the plants.
question

Photosynthesis
answer

Some of the sugar is used right away by the plant for energy; some is stored as starch; and some is built into plant tissue
question

Importance of Photosynthesis to Humans
answer

We cannot make our own food (glucose, energy), we must get our food from plants.
question

Plants
answer

The first step in the food chain.
question

Oxygen
answer

Released during photosynthesis; is necessary for all living things.
question

Cellular Respiration
answer

The release of chemical energy for use by cells.
question

Cellular Respiration
answer

Once the energy that was in sunlight is changed into chemical energy by photosynthesis, an organism has to transform the chemical energy into a a form that can be used by the organism.
question

Cellular Respiration
answer

The breakdown of glucose molecules to release energy.
question

Cellular Respiration
answer

Takes place in all living things.
question

Cellular Respiration
answer

Is a step by step process.
