1. Photosynthesis and Cellular Respiration

2. Photosynthesis & Cellular Respiration
How is energy being obtained by the organisms?
Plant
Caterpillar
Which organisms uses photosynthesis to obtain energy?
Can you see the vascular (vessel) system of the plant?

3. What does reactants mean?
What are the reactants of photosynthesis? (what things are going into the plant?)
Ingredients.
Sunlight (energy), carbon dioxide, and water.

4. Reactants for Photosynthesis

5. Review Question What are organelles again?
Organelles are structures that do certain jobs in a cell.

6. Where does photosynthesis happen?
Inside organelles in plant cells called chloroplasts. They have something called chlorophyll which captures sunlight.

7. What are products?
What are the products of photosynthesis?
Products are things that are made.
Sugar and oxygen.

14. What about organisms that can NOT make their own food?
Consumers such as animals can’t make their own food.
Plants AND Animals undergo another process called …
Cellular Respiration
in which they turn Glucose (A.K.A. sugar) into.
Energy

15. What do organisms need energy for?
To catch food and to run from predators
To stay warm during cold weather
To carry out life processes such as breathing, digesting food, transporting nutrients, etc
All of the above

17. What is cellular respiration?
Cellular respiration is how organisms take the sugar, and break it apart to get the energy stored inside the sugar.

18. What is the original source of energy for all living things (plants and animals)?
Nutrients in the soil feed plants and plants pass the energy onto consumers.
Plants use water to gain nutrients and then pass the energy onto consumers.
Plants make their own food using energy from sunlight and pass this energy onto consumers.
Consumers are able to get energy from eating plants and when they die, give energy back.

29. Products of Cellular Respiration

30. Critical Thinking
Energy is one of the products of cellular respiration. What’s different about that energy from the energy that was the reactant of photosynthesis?
The energy is still the energy that came from the sun but it’s just in a different form.

31. Critical Thinking
Whenever you eat anything, the energy you get from that food is the same energy as the energy from the sun.
It’s just in a different form.
When you eat sunflower seeds, you get energy (calories) from them. The sunflower got that energy from the sun.

32. The energy is just in a different form
The energy is just in a different form. Energy can change forms like play-doh. When you have play-doh it can be made into many different shapes, but it’s the same play-doh.
The energy you get from eating sunflower seeds is in the form of calories, but it’s the same energy as the energy that came from the sun, except when the plant got it, it was in the form of sunlight.
