QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Plant Transport Systems.
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 exposed to high wind and low humidity. Predict the effect on its rate of transpiration.
A plant is placed in a solution with a higher solute concentration than its cell sap. What will happen to the plant cells?
Describe how mineral ions are absorbed by plant roots.
Describe how temperature affects the rate of transpiration in plants.
Describe the pressure-flow hypothesis for phloem transport.
Describe the role of lignin in xylem vessels.
Describe the role of root pressure in plant water transport.
Explain how guard cells regulate the opening and closing of stomata.
Explain the cohesion-tension theory of water transport in plants.
Explain the difference between source and sink in phloem transport.
Explain why the phloem requires living cells for its function, while the xylem does not.
Explain why wilting occurs in plants.
