What are the things that you cannot live without?

1. What are the things that you cannot live without?

2. Photosynthesis

3. Do plants eat cheeseburgers? • Heterotroph • Autotroph

4. Do plants eat cheeseburgers? • Heterotroph • “other feeder” • Has to consume other organisms to get energy • Autotroph

5. Do plants eat cheeseburgers? • Heterotroph • “other feeder” • Has to consume other organisms to get energy • Autotroph • “self-feeder” • Has the ability to make its own fuel to get energy

7. Conservation of Energy • Energy cannot be created or destroyed, it can only be converted to a different form. • What does this mean for plants?

8. Conservation of Energy • Energy cannot be created or destroyed, it can only be converted to a different form. • What does this mean for plants? • Plants cannot just create their own energy from nothing

9. Plants get their energy from the Sun

10. Plants cannot just use light energy directly, they have to convert it to a usable form first!

11. PHOTOSYNTHESIS!

12. Photosynthesis Equation Carbon Dioxide + Water => Sugar + Oxygen CO2 + H2O => CH2O + O2

13. Photosynthesis Equation Carbon Dioxide+Water=>Sugar+Oxygen CO2 + H2O => CH2O + O2 Don’t be scared! We will be going over this in more detail later

15. This would be a slide with the plant leaf and chloroplast diagrams from their textbook

16. Plant Parts Summary • Stomata are pores in the leaf that regulate CO2 intake and O2 output • Mesophyll Cells are cells at center of leaf cell layers which contain chloroplasts A Chloroplast is the organelle where photosynthesis takes place! • Thylakoid = chlorophyll is located in the thylakoid membrane • Granum (plural: grana) = stack of thylakoids • Stroma = area outside grana where complex sugars are created

17. Pigments • Chlorophyll is a pigment that absorbs sunlight and incorporates the energy into the process of photosynthesis • Chlorophyll is not the only pigment that exists in a leaf • What happens to the leaves in fall?
