Plant Physiology starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Plant Physiology.
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
A plant is placed in a dark room for several days. What will happen to its rate of photosynthesis?
Describe the difference between xylem and phloem.
Describe the process of osmosis in plant cells.
Explain how temperature affects the rate of photosynthesis.
Explain the importance of mineral nutrients in plant growth.
Explain the role of guard cells in plant physiology.
Explain why wilting occurs in plants.
Name the pigment responsible for absorbing light during photosynthesis.
What are the two main products of photosynthesis?
What is the main function of root hairs?
What is the main function of stomata in leaves?
What is the main function of the cuticle in leaves?
What is the role of sunlight in photosynthesis?

A potted plant is kept in a sealed transparent container with adequate water but no air holes. After several hours in sunlight, what changes would you expect in the levels of oxygen and carbon dioxide inside the container? Explain your answer.
A student sets up an experiment to measure the rate of photosynthesis in two identical plants. One plant is placed under red light and the other under green light. Predict which plant will have a higher rate of photosynthesis and explain why.
Describe the role of ATP in the process of photosynthesis.
Explain how water potential affects the movement of water between plant cells and their environment.
