According to the 'Drought' section, which of the following is NOT a described physiological or morphological response that plants use to cope with water deficits?

  • A: Reducing the rate of transpiration by closing stomata.
  • B: Increasing the synthesis and release of abscisic acid to keep stomata closed.
  • C: Rolling leaves into a tubelike shape to reduce exposed surface area.
  • D: Significantly increasing photosynthetic activity to maximize water uptake.
  • E: Shedding leaves in response to seasonal drought.

Explanation

The 'Drought' section explicitly mentions several coping mechanisms: reducing transpiration by closing stomata, increasing abscisic acid synthesis, rolling leaves into a tubelike shape, and shedding leaves. It also states that 'a drought diminishes crop yield' and reduces photosynthesis, meaning increased photosynthetic activity is not a coping mechanism but rather a process negatively affected by drought.
