Question

Given below is an apparatus which was setup to investigate a physiological process in plants. The setup was placed in bright sunlight. Answer the questions that follow:

1. Name the process being studied. Define the process.
2. Why was the pot enclosed in a rubber sheet?
3. Mention two external factors which can accelerate the above process.
4. List two adaptations in plants to reduce the above process.
5. Draw a neat, labelled diagram of a stomatal apparatus.

Answer 1

1. The process being studied is Transpiration. Transpiration is the process during which water is lost in the form of water vapour through the aerial parts of the plant.
2. The pot was enclosed in a rubber sheet to prevent evaporation of water from the soil.
3. Two external factors which can accelerate transpiration are:
   1. Bright sunlight
   2. Low humidity
4. Two adaptations in plants to reduce the above process are:
   1. Sunken stomata
   2. Narrow leaves
5.
