Read each question carefully and provide your answers in the spaces provided. Refer to the diagram of photosynthesis as needed.
Observe the diagram below, which illustrates the overall process of photosynthesis.
1. Photosynthesis is the process by which green plants and some other organisms use to synthesize foods from carbon dioxide and water.
2. The primary pigment responsible for absorbing light energy in plants is .
3. The light-dependent reactions of photosynthesis occur in the membranes of the chloroplast.
4. The Calvin cycle, also known as the light-independent reactions, takes place in the of the chloroplast.
1. Which of the following is NOT a product of the light-dependent reactions?
ATP
NADPH
Oxygen
Glucose
2. What is the primary function of the Calvin cycle?
To produce ATP and NADPH
To convert light energy into chemical energy
To fix carbon dioxide into organic molecules
To release oxygen into the atmosphere
1. Briefly explain the role of water in the light-dependent reactions of photosynthesis.
2. Describe the main difference between C3 and C4 photosynthesis pathways.
1. The products of photosynthesis are glucose and carbon dioxide.
True
False
2. Chlorophyll absorbs all wavelengths of visible light equally.
True
False
