Student-friendly explanation

Plants do not have special excretory organs like animals. They remove wastes by storing them in vacuoles, leaves, bark, fruits, or by releasing gases and water vapour. Some wastes are also dropped when leaves, bark, or fruits fall off.

How to write this in exams

  1. 1

    Start with the exact idea

    Excretion in plants is the removal or storage of waste substances produced during life processes.

  2. 2

    Then show how to use it

    1. State that plants produce wastes. 2. Mention storage sites. 3. Mention release through stomata or lenticels. 4. Add leaf fall or bark shedding. 5. Conclude with no special organ needed.

  3. 3

    Add one concrete example

    A plant may store resins or gums in old tissues, and oxygen from photosynthesis may leave through stomata.

  4. 4

    Avoid this incomplete answer

    Plants do not produce wastes. This is wrong because plants do produce wastes, but they remove them differently from animals.

Definition

Excretion in plants is the removal or storage of waste substances produced during life processes.

Example

A plant may store resins or gums in old tissues, and oxygen from photosynthesis may leave through stomata.

Rule to remember

Rule: Plant wastes are usually stored, diffused out, or shed with plant parts.

Memory hook

Plants store, release, or shed wastes.

Examples and method

Worked example

A neem tree may store some waste in leaves and bark. When old leaves fall, those wastes are removed from the plant.

Method to apply

1. State that plants produce wastes. 2. Mention storage sites. 3. Mention release through stomata or lenticels. 4. Add leaf fall or bark shedding. 5. Conclude with no special organ needed.

Diagram support

A simple flow diagram can show wastes moving to leaves, bark, vacuoles, or escaping through stomata.

How CBSE asks it

Explain how plants excrete, list methods of waste removal, or compare plant excretion with human excretion.

Avoid common mistakes

Common confusion

Students think plants have no waste products at all.

Common wrong answer

Plants do not produce wastes. This is wrong because plants do produce wastes, but they remove them differently from animals.

Exam tip

Mention storage, diffusion, leaf fall, and release through stomata in your answer.

Quick check

How do plants often get rid of wastes stored in old leaves or bark?

Plants often get rid of such wastes by shedding old leaves, bark, or fruits, so the stored waste leaves the plant body.
