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 10
A plant is placed in a sealed container with only water and sunlight. After several hours, what change would you expect in the oxygen level inside the container?
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. Explain why this happens.
Describe one adaptation of leaves that helps maximize photosynthesis.
Describe what happens to glucose produced during photosynthesis.
Explain the relationship between photosynthesis and cellular respiration.
Explain why photosynthesis is important for life on Earth.
