The importance of exchange surfaces and transport systems in plants

Biology

Pupils will learn about ways in which the human body maintains a constant internal environment in response to internal and external change, including changes in temperature and water balance.

Pupils learned about aerobic and anaerobic cellular respiration, including the chemical reactants and products of the processes, and practical ways to measure the rate of cellular respiration in living cells.

Transport and exchange surfaces in plants

To transport nutrients produced by photosynthesis.

To transport water and minerals from the roots to the rest of the plant.

Which cells increase the surface area for water and mineral uptake in roots?

To transport sugars produced by photosynthesis.

To transport water and minerals from the roots.

What is the main function of phloem in plants?

They allow gases to move in and out of the leaf.

They increase the surface area for water absorption.

They transport nutrients throughout the plant.

What role do stomata play in the process of gas exchange in leaves?

Which of the following are phloem responsible for transporting?

Sugars and amino acids into and out of the phloem

Water into the root hair cells from the soil

Match the transport method to where it occurs in a plant.

from an area of lower concentration to an area of higher concentration.

through a selectively-permeable membrane.

from an area of higher concentration to an area of lower concentration.
