4. GLE
GLE Distinguish between the basic features of photosynthesis and respiration.

5. Photosynthesis
Grade 7 Science

6. What is photosynthesis?
Process plants use to make their own food
Some plants cells contain chlorophyll
Chlorophyll (green color) makes photosynthesis possible
It occurs in the chloroplast

7. The chlorophyll absorbs the sunlight.

8. The sunlight is combined with water, Carbon Dioxide and nutrients from the soil.

9. 6CO2 + 12H2O + light energy   C6H12O6 + 6O2
The chlorophyll processes the ingredients and makes sugar (plant food) and oxygen.
Sugar + Air O2

10. Equation for Photosynthesis
6CO2 + 6H2O + Sunlight  C6H12O6 + 6O2
Reactants  Products

11. Reactants Reactants are what you start with in a chemical reaction.
These are the substances that enter into a chemical reaction.

12. Products Products are what you end with in a chemical reaction.
Products are substances which form as a result of a chemical reaction.

13. Plants and animals need each other to survive.

14. Animals including humans make the CO2 (carbon dioxide) plants need
Animals including humans make the CO2 (carbon dioxide) plants need. They (the plants) make the O2 (oxygen) and food we need.

15. Cellular Respiration
The process by which cells use oxygen to produce energy from food.
It occurs inside the Mitochondria

16. Cellular Respiration Equation
C6H12O6 + 6O2  6CO2 +6H2O + Energy (ATP) Reactants  Products

17. Science Closure 2/19/18
What does a plant need to make sugar through photosynthesis?
soil, water, and oxygen
carbon dioxide, sunlight, and soil
C. oxygen, sunlight, and soil
D. sunlight, water, and carbon dioxide

18. Science Closure 2/19/18 What are the reactants for photosynthesis?
2. What are the products of photosynthesis?
3. What organelle does photosynthesis take place in?

19. Closure
What part of a plant can perform photosynthesis? A. only the leaves B. only the stem C. only the roots D. any cell with chlorophyll
