Introduction

Transpiration is one of the natural processes vital for a plant's survival. Without transpiration, a plant will not be able to suck up water from the roots to reach every nook and corner of the plant. In this simple experiment, we observe the effects of transpiration by covering a few leaves of a living plant with an airtight transparent polythene bag.

Tools

Parts

  1. Identify a nice outdoor plant with big leaves.
    • Identify a nice outdoor plant with big leaves.

    • Cover a few leaves of the plant with a transparent polythene bag with the help of a rubber band.

    • Make sure it is airtight, but not so tight so as to suffocate the covered leaves/stem.

    • Leave this setup for 3 hours in the Sun.

    • Make observations every hour.

    • What do you see?

    It would be nice to get a few more pictures at these first couple of steps

  2. Within 2-3 hrs, you should find some water droplets condensing within the poly bag.

    • Where is this water coming from? How?

    Vishal:

    1) We don't need to add transpiration definition here.

    • Plant leaves are not fresh enough and/or covered in dust.

    • Plant not placed in the outdoors where there is adequate sunlight.

    • Polythene bag not airtight around the leaves.

    • Weather conditions not optimal for transpiration, e.g. too rainy or too cold.

    • Why do we observe moisture when we tie a polythene bag to a plant(leaf) ?

    • What happens when a plant is kept in a dark place instead of under the sunlight?
