3. Photosynthesis
Process where radiant energy (from the sun) is used to turn water and carbon dioxide into chemical energy (glucose).
Oxygen is a plant’s waste product that is released during this process.

4. Formula for photosynthesis
Copy the full formula, with compounds and names

5. Question: Is photosynthesis a physical or chemical reaction?
READ ONLY
Is photosynthesis a physical or chemical reaction?
Physical Change
Chemical Change
Changes size/shape
Permanent
Dissolves
Creates a new substance
Changes phase
Gas production (bubbles)
Unexpected color change
Temperature change

6. Answer:
Photosynthesis is a chemical reaction because it creates new substances
Oxygen and Glucose (sugar) are NEW substances, the PRODUCTS of photosynthesis

7. Chloroplasts Chlorophyll
are the organelles of a plant cell WHERE photosynthesis occurs.
Chloroplasts are in plant cells ONLY (plants can photosynthesize while animals cannot)
Chlorophyll
is the chemical in chloroplasts that give plants their green color.

8. Each plant cell has NUMEROUS chloroplasts.

9. Stoma
Openings/spaces on the undersides of leaves that allows gas exchange.
This allows Carbon Dioxide to enter the leaf and allows Oxygen to be given off as waste)
The problem is that the air spaces in the leaf are saturated with water, which exits the leaf through the stomata. Therefore, plants cannot gain carbon dioxide without simultaneously losing water.

10. Why is photosynthesis important to us?
Consumers get their energy from eating producers
90% of ALL oxygen on Earth is produced through Photosynthesis

12. Reactants and Products
REACT TO START A REACTION
PRODUCTS
ARE PRODUCED (made) during a reaction
LABEL THE REACTANTS AND PRODUCTS IN THE PHOTOSYNTHESIS FORUMULA
