Answer 2

Both assertion and reason are CORRECT,but reason is NOT THE CORRECT explanation of assertion for stomatal pores.

• Stomata is concerned with exchange of gases in the process of respiration and photosynthesis. Loss of water also occurs during transpiration.
• Guard cells open and close due to change in ionic and water concentration.
• Usually stomatal pores open during day, but in desert areas, they open during night.
• The latter case occurs to reduce water loss.
