Lenticular transpiration is ___________ of total transpiration?
Correct answer: D. 1-2%
- A. 2-3%
- B. 1-3%
- C. 1-4%
- D. 1-2%
Explanation
Lenticular transpiration through bark lenticels is usually about 1% to 2% of total transpiration, so option d gives the standard approximate range. Students may choose 2% to 3% because lenticels are visible openings, but most water loss occurs through stomata rather than lenticels.

About Biological Importance of Water
Water supports life through its polarity, hydrogen bonding and ability to dissolve ionic and polar substances. Its high specific heat, heat of vaporization, cohesion, adhesion and incompressibility help regulate temperature, transport materials and maintain structure, while hydrolysis and osmosis depend directly on water.
