Photosynthesis & Respiration
![Page 2: Photosysthesis](https://reader033.fdocuments.us/reader033/viewer/2022042813/545c991bb0af9f12318b4967/html5/thumbnails/2.jpg)
What is Photosynthesis?
The process of photosynthesis is a chemical reaction.
It is the most important
chemical reaction on our planet.

Chemical Reaction of
Photosynthesis?

What is the equation for the chemical reaction of
photosynthesis?

What is the equation for the chemical reaction of
photosynthesis?
Six molecules of carbon dioxide react with six molecules of water to form 1 molecule of
glucose and six molecules of oxygen.

Describe Photosynthesis

Describe Photosynthesis
• The process of changing light energy to chemical energy
• Energy stored as sugar
• Occurs in plants and some algae
• Plants need light energy, CO2, and H2O
• Takes place in the chloroplasts, using chlorophyll, the green pigment in plants

What happens during photosynthesis?
![Page 9: Photosysthesis](https://reader033.fdocuments.us/reader033/viewer/2022042813/545c991bb0af9f12318b4967/html5/thumbnails/9.jpg)
What happens during photosynthesis?
• Plants capture light energy and use that energy to make glucose
• Sunlight provides the energy needed by chlorophyll to change molecules of carbon dioxide and water into glucose
• Oxygen is also released in this reaction

What happens during photosynthesis?
• Carbon dioxide enters the leaf through holes called stomata
• CO2 combines with the stored energy in the chloroplasts through a chemical reaction to make glucose
• The sugar is moved through tubes in the leaf to the roots, stems and fruits of the plants
• 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

Why is this important to us?
![Page 12: Photosysthesis](https://reader033.fdocuments.us/reader033/viewer/2022042813/545c991bb0af9f12318b4967/html5/thumbnails/12.jpg)
Why is this important to us?
We cannot make our own food (glucose, energy), we must get our food from plants.
Plants are the first step in the food chain.

Why is this important to us?
The oxygen released during photosynthesis is necessary for all living things.

What is Cellular Respiration?
![Page 16: Photosysthesis](https://reader033.fdocuments.us/reader033/viewer/2022042813/545c991bb0af9f12318b4967/html5/thumbnails/16.jpg)
What is Cellular Respiration?
The release of chemical energy for use by cells.

What is Cellular Respiration?
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.
This process is cellular respiration.

Describe Cellular Respiration
• The breakdown of glucose molecules to release energy
• Takes place in all living things
• Is a step by step process
