1. What is the importance of the light and dark reactions in photosynthesis?
Photosynthesis works by absorbing light. Our sun gives off energy and the chlorophyll from the plant absorb this energy. The energy is then used to separate water into hydrogen and oxygen and then they combine hydrogen and carbon dioxide to make sugars.
2. What happens to food energy during photosynthesis? During cellular respiration?
In Photosynthesis light energy along with carbon dioxide are used to make molecules or (food energy). In Cellular Respiration food energy is broken down to form ATP.
3. Why is photosynthesis important to you?
Photosynthesis is important because plants, bacteria, and small animals use photosynthesis to eat. Photosynthesis converts light energy into sugars and other proteins which are need for the plants, bacteria, and small animals to survive.
4. What are the processes in cellular respiration?
Cellular Respiration is a process by which cells obtain energy from glucose. Cells are broken down into simple food molecules. Cellular Respiration undergoes two processes: Glycolysis and The Krebs Cycle. In Glycolysis enzymes help in chemical reactions that break down oxygen and glucose into different molecules. Pyruvic and 2 molecules of ATP are produced during Glycolysis. In the Krebs cycle nine reactions occur. Pyruvic acid is broken down and carbon dioxide and energy are given off. This energy is then used to create ATP and water.
5. Why are photosynthesis and cellular respiration viewed as complementary processes?
They are complementary process because they both need the same components, water, energy, carbon dioxide, and glucose.
6. Describe the similarities and differences between photosynthesis and cell respiration.
Differences- Photosynthesis gives off oxygen while cellular respiration uses oxygen.... [continues]
