Question

A well watered plant growing under sufficient sunlight was covered with the polythene and tied just above the roots. After 3 to 4 hours, it was observed that a lot water droplets were present inside the polythene bag. Which process may have contributed to this?

• A. Pollination
• B. Transpiration
• C. Venation
• D. Photosynthesis

Answer 1

The correct option is B Transpiration

$\bullet$ The presence of water droplet inside the polythene was due to transpiration. Transpiration is the process through which the excess water is released through stomata in the form of water vapour.
$\bullet$ Pollination is the act of transferring pollen grains from the anther of a flower to the stigma to create offspring for the next generation.
$\bullet$ The arrangement of veins in the lamina of the leaves is known as venation.
​​​​​​​ $\bullet$ Photosynthesis is the process by which green plants prepare food in the presence of sunlight, carbon dioxide and the green pigment chlorophyll.
