Question
What is the primary pigment in plants that captures sunlight?
Answer
Chlorophyll
3
Question
What is the role of chlorophyll in photosynthesis?
Answer
Chlorophyll absorbs light energy that is used to convert carbon dioxide and water into glucose and oxygen.
4
Question
What are the two stages of photosynthesis?
Answer
The light-dependent reactions, which take place in the thylakoid membrane and produce ATP and NADPH, and the light-independent reactions or the Calvin cycle, which take place in the stroma and produce glucose.
5
Question
Where do the light-dependent reactions take place?
Answer
Thylakoid membrane
6
Question
Where do the light-independent reactions take place?
Answer
Stroma
7
Question
What is the function of ATP in photosynthesis?
Answer
ATP is used as an energy source to fuel the light-independent reactions of photosynthesis.
8
Question
What is the function of NADPH in photosynthesis?
Answer
NADPH is used as a reducing agent in the light-independent reactions of photosynthesis to convert carbon dioxide into glucose.
9
Question
In what types of cells does photosynthesis occur?
Answer
Photosynthesis occurs in plant cells, algae, and some types of bacteria (such as cyanobacteria).
10
Question
What is the importance of photosynthesis?
Answer
Photosynthesis is important because it is the process by which green plants and some other organisms produce the oxygen we breathe and the food we eat. It is also the basis of almost all life on Earth, as it provides the energy and organic matter that most other organisms rely on.
