Plant Transport Systems starts at 7 and continues till grade 12.
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 8

Describe how minerals are absorbed by plant roots.
Describe the difference between source and sink in the context of phloem transport.
Describe the role of guard cells in plant transport systems.
Describe the role of phloem in plants.
Explain how root hair cells help in the absorption of water.
