Which of the following plant adaptations is typically observed in plants growing in water-scarce environments (xerophytes) to minimize transpirational water loss?
- A.Stomata distributed equally on both upper and lower epidermis in large numbers
- B.Presence of a thick, cuticular layer on leaf surfaces and sunken stomataCorrect answer
- C.Broad, thin lamina with massive intercellular air spaces
- D.Absence of root hairs to prevent excessive water absorption
Solution
Xerophytes possess specific adaptations such as thick cuticles on their leaf surfaces and sunken stomata to reduce transpiration losses. Broad thin lamina and large air spaces are characteristics of hydrophytes.
