Leaves or entire plant looks droopy.

• A. Wilting
• B. Discoloration
• C. Underdevelopment
• D. Chlorosis

Answer: (A)

The main concept here is plant turgor and wilting. Leaves and stems stay erect because plant cells are turgid—full of water—that creates internal pressure that keeps tissues stiff. When water is not available or the plant cannot move water to the tissues effectively, cells lose water, turgor drops, and the plant tissues slacken, causing a droopy appearance. That drooping is what we call wilting, and it signals the plant needs water or has a transport issue, especially under heat, drought, or a restricted root zone. Other terms describe different problems: discoloration refers to color changes from pigment or nutrient issues; underdevelopment means stunted growth; chlorosis specifically means yellowing from chlorophyll loss. So droopy leaves point to wilting due to loss of turgor.
