When a flower is described as wilt-sensitive or dry-prone, what does this refer to?

• A. They wilt easily and transpire rapidly, losing turgidity and shedding florets/leaves.
• B. They are resistant to wilting.
• C. They dry out quickly but keep turgidity.
• D. They just look droopy but are fine.

Answer: (A)

Wilting happens when water loss exceeds what the plant can replace, causing turgor pressure in the cells to drop and the tissues to lose firmness. Wilt-sensitive or dry-prone flowers are those that cannot hold their rigidity because they transpire quickly and cannot sustain water uptake. The rapid water loss means cells become flaccid, so the flower droops and florets or leaves may shed as part of the stress response. That’s why the description “they wilt easily and transpire rapidly, losing turgidity and shedding florets/leaves” best matches this trait. The other statements don’t fit because wilting resistance would mean they stay firm, drying out quickly would typically reduce turgidity rather than preserve it, and simply looking droopy doesn’t address the actual loss of turgor from water stress.
