Transportation in plants is the movement of water, minerals, and food through xylem and phloem.

Practice This Concept

Learn the concept

Student-friendly explanation

Roots absorb water and minerals from the soil. Xylem carries water upward, while phloem carries prepared food from leaves to other parts. Transport in plants is slower than in animals, but it is essential for growth and survival.

How to write this in exams

  1. 1

    Start with the exact idea

    Transportation in plants is the movement of water, minerals, and food through xylem and phloem.

  2. 2

    Then show how to use it

    1. Identify the substance. 2. Choose xylem or phloem. 3. State the direction. 4. Relate it to roots and leaves. 5. Add an observation example.

  3. 3

    Add one concrete example

    Water absorbed by roots moves to leaves, and sugar made in leaves moves to roots and fruits.

  4. 4

    Avoid this incomplete answer

    Phloem carries water upward. This is wrong because xylem carries water, while phloem carries food.

Definition

Transportation in plants is the movement of water, minerals, and food through xylem and phloem.

Example

Water absorbed by roots moves to leaves, and sugar made in leaves moves to roots and fruits.

Rule to remember

Rule: Xylem mainly carries water and minerals; phloem mainly carries food made in leaves.

Memory hook

Xylem lifts water; phloem shares food.

Examples and method

Worked example

If a plant is placed in coloured water, the colour rises through the stem because xylem carries water upward.

Method to apply

1. Identify the substance. 2. Choose xylem or phloem. 3. State the direction. 4. Relate it to roots and leaves. 5. Add an observation example.

Diagram support

Label roots, stem, and leaves; show xylem and phloem with arrows for upward water movement and food movement to other parts.

How CBSE asks it

Differentiate xylem and phloem, explain movement of water in plants, or describe the role of transport tissues.

Avoid common mistakes

Common confusion

Students confuse xylem with phloem or think both carry the same substance.

Common wrong answer

Phloem carries water upward. This is wrong because xylem carries water, while phloem carries food.

Exam tip

Remember xylem for water and phloem for food.

Quick check

What does xylem transport in a plant?

Xylem transports water and dissolved minerals from the roots to the rest of the plant, especially upward toward the leaves.

Answer writing and exam use

1-mark answer
