Journal Questions:

1. What is the importance of the light and dark reactions in photosynthesis?

Light Dependent Reaction is the initial stage of Photosynthesis Where solar energy is converted into potential energy, the light Dependent Reaction produces oxygen gas and converts ADP and NADP+ into ATP and NADPH

Dark Reaction takes place in Stoma of the chloroplasts in photosynthetic plants, Energy from light are stored has ATP and NADPH .in Calvin cycle this stored energy is used to make sugar molecule, the Calvin cycle is a complex theory of chemical reactions carried out in stoma.

2. What happens to food energy during photosynthesis? During cellular respiration?

Food energy is broken down to form ATP during cellular respiration. Although the process requires energy, more is made than is used up.

Photosynthesis is the opposite. Light energy along with carbon dioxide and CO2 are used to make organic molecules i.e. food energy.

3. Why is photosynthesis important to you?

When photosynthesis occurs, it produces oxygen as well as glucose both of those things are needed for cellular respiration in humans. Cellular respiration produces energy which humans need to survive. Plants require carbon dioxide which is produced by cellular respiration in humans.

4. What are the processes in cellular respiration?

Glycolysis and the Krebs cycle

5. Why are photosynthesis and cellular respiration viewed as complementary processes?

Because they both create ATP (Energy) (or they function as a circle one creating CO2 and using O2, and the other Using O2 and creating CO2)

6. Describe the similarities and differences between photosynthesis and cell respiration.

Photosynthesis

1. Produces food.

2. Stores energy.

3. Occurs in cells containing chloroplasts.

4. Releases oxygen.

5. Uses water.

6. Uses carbon dioxide.

7. Occurs in sunlight.

Respiration

1. Uses food...
