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 9

Describe the relationship between photosynthesis and respiration in plants.
Describe the role of water in photosynthesis.
Explain how temperature affects the rate of photosynthesis.
Explain why photosynthesis is important for life on Earth.
Explain why plants need both mitochondria and chloroplasts.
A plant is placed in a dark room for 48 hours. Will it continue to photosynthesize? Yes or No.
