What are basic functions of organisms? 1- getting food 2- getting energy from that food 3-using the energy from that food and letting go of things that are no longer needed like wastes
We are like our cells only bigger. Because we need these basic functions our cells need them also. If our cells are thirsty, we go get a drink. If our cells are hungry, we go get food. If our cells need to get rid of wastes, we go to the bathroom.
How do our cells get food? Animal cells get food when we go to McDonalds and eat food. Heterotroph. Plant cells can’t send the plant to McDonalds, they turn to the sun and absorb the suns radiant energy to make their food. Autotroph.
Its sort of like making a cake Ingredients Bake it Out comes cake Carbon dioxide + water + light sugar + oxygen (6CO2 + 6H2O + energy yields C6H12O6 + 6O2) Food structures Energy for plant Storage (potatoes /carrots)
Photosynthesis quiz 1. What is ‘light putting together’ ? 2. Name three things that are required for photosynthesis? 3. Where do these three things ‘meet’ for photosynthesis to happen? 4. How does CO2 get into the plant? 5. How does energy get into the plant? 6. What two things does the plant get after mixing these three things? 7. What does it do with each of these two things? 8. What is the chemical equation for photosynthesis? 9. What is C6H12O6 ? 10. The arrow means? A. Yields B. 6CO2 +6H2O+energy C6H12O6+O2 C. Carbon Dioxide, Water & Energy D. Sugar E. Photosynthesis F. Sugar- food for energy Oxygen-waste G. Sugar & Oxygen H. In the green pigment called chlorophyll inside the chloroplast organelle. I. Stomata J. Absorbed by the Chlorophyll in the Chloroplast
7. Look real close at this chemical formula. How is it different than photosynthesis? C6H12O6+6O2 6CO2+6H2O+energy? Just the opposite of photosynthesis.
How cells use the energy they get through photosynthesis
