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 8
A plant is placed in a dark room for a week. What will happen to its rate of photosynthesis?
A student sets up an experiment with two identical plants. Plant A is kept in sunlight, and Plant B is kept in darkness. After a week, Plant A is healthy, but Plant B is wilted and yellow. What is the most likely reason for this difference?
Describe the role of stomata in photosynthesis.
Explain how photosynthesis helps maintain the balance of oxygen and carbon dioxide in the atmosphere.

The overall chemical equation for photosynthesis is:
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
What does C6H12O6 represent?
What would happen to the oxygen level in the atmosphere if all plants stopped photosynthesizing?
Which of the following best describes the process of photosynthesis?
(1) Plants use oxygen to make food
(2) Plants use sunlight to convert carbon dioxide and water into glucose and oxygen
(3) Plants absorb nutrients from the soil to make food
