The vascular tissues in higher plants are responsible for

Analyze the question The question asks what the vascular tissues (xylem and phloem) do in higher plants.

Explain the concept Vascular tissues are the "transport system" of higher plants:

• Xylem carries water and dissolved mineral salts from the roots up to the stems and leaves. It also gives mechanical support.
• Phloem carries manufactured food (mainly sucrose and amino acids) from the leaves to other parts of the plant, such as roots, fruits and storage organs. This is called translocation.

Go through the options

• A. the movement of food and water: Correct. Phloem moves food and xylem moves water.
• B. suction pressure: This is a force related to water uptake by cells. It is not the function of the tissues.
• C. transpiration pull: This is the force that drags water up the xylem, caused by evaporation from the leaves. It is a process, not the overall role of vascular tissue.
• D. the transport of gases and water: Gases move mainly by diffusion through stomata, lenticels and intercellular air spaces, not through vascular tissue.

Answer The vascular tissues are responsible for the movement of food and water, which is option A.

Exam tip Remember "X for water, P for food": Xylem = water (up), Phloem = food (up and down). If an option mentions gases being transported, think of stomata and diffusion, not xylem or phloem.
