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 7
A plant is kept in a very dry environment. Predict what will happen to its rate of transpiration.
A plant is placed in a solution with a lower water concentration than its root cells. What will happen to the plant?
Describe how water moves from the soil into the root hair cells.
Describe the role of root hairs in plant transport systems.
Describe what would happen if a plant's phloem was damaged.
Explain how minerals are transported from the soil to the leaves of a plant.

Fill in the blank: The movement of food through the phloem is called __________.
Fill in the blank: The movement of water through a plant from the roots to the leaves is called the __________ stream.
Fill in the blank: The process by which plants lose water vapor through their leaves is called __________.
Fill in the blank: The process by which plants transport food from leaves to other parts is called __________.
True or False: Phloem only transports food downwards in the plant.
True or False: The cortex is responsible for transporting water in plants.
True or False: The movement of water in plants is always passive and does not require energy.
True or False: The phloem can transport substances both upwards and downwards in the plant.
