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 9
A plant is exposed to strong wind. Predict how this will affect its rate of transpiration.
A plant is placed in a humid environment. Predict how this will affect its rate of transpiration.
A student observes that a plant's leaves are drooping. Which plant transport process is most likely not functioning properly?
Describe how water moves from the soil into the root hair cells.
Describe the function of phloem in plants.

Fill in the blank: The loss of water vapor from the aerial parts of a plant is called __________.
Fill in the blank: The main force that moves water up the xylem is called __________ pull.
Fill in the blank: The opening and closing of __________ control the rate of transpiration in leaves.
Fill in the blank: The process by which food is transported in plants is called __________.
True or False: Phloem transport is bidirectional.
True or False: The movement of water in the xylem is a passive process.
True or False: The movement of water through the plant is called translocation.
True or False: The phloem can transport substances both upwards and downwards in the plant.
