Photosynthesis
Biology ⇒ Plant Biology
Photosynthesis starts at 6 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Photosynthesis.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A plant is placed in a sealed container with only water and light. After several hours, the oxygen concentration in the container increases. What process is responsible for this change?
A scientist measures the rate of photosynthesis in a plant at different temperatures. She finds that the rate increases up to 30°C, then decreases at higher temperatures. What could explain this observation?
Describe how increasing carbon dioxide concentration affects the rate of photosynthesis.
Describe one way in which C4 plants differ from C3 plants in terms of photosynthesis.
Describe the role of NADP+ in photosynthesis.
Explain the role of water in the light-dependent reactions of photosynthesis.

Fill in the blank: The light-absorbing molecules in plants are called _______.
Fill in the blank: The main function of ATP synthase in photosynthesis is to produce _______.
True or False: All plants use the same pathway for carbon fixation during photosynthesis.
True or False: ATP and NADPH produced in the light-dependent reactions are used in the Calvin cycle.
True or False: Photosynthesis occurs only during the daytime.
True or False: The Calvin cycle requires light to function.
