Transpiration In Plants
To study how do plant transpire
potted plant (at least with 2-3 branch), two transparent polythene bags and
some string or thread.
Take a healthy potted plant.
2. Enclose a leafy branch of the plant in a polythene
bag and tie up its mouth tightly using string.
3. Remove leaves from the other branch of the plant and
enclose branch without leaves in polythene bag and tie up its mouth tightly
4. Now keep the plant in sun for few hours.
5. Bring back the plant after few hours and observe the
change in plant.
see that there are water droplets on the inner side of the polythene bag in
which the leaves are intact. There are no water droplets in the polythene bag without
comes out of leaves in the form of vapor by a process called transpiration.
Plants release a lot of water into the air through this process.
