If light is not sufficient, a plant will develop

• A. Flower
• B. Dwarfism
• C. Necrosis
• D. Etiolation

Answer: (D)

When light is scarce, plants exhibit etiolation, a growth response aimed at reaching more light. This shows up as elongated, leggy stems and a pale, yellowish color because there isn’t enough light for robust chlorophyll production. Leaves become small and spaced far apart, and overall the plant appears stretched and weak. Flowering isn’t a direct result of low light; many species actually rely on light cues to trigger flowering, and necrosis describes tissue death from damage or disease, not a normal low-light response. Dwarfism would mean stunted, compact growth, which isn’t what happens when light is insufficient. To reverse etiolation, increase light intensity or duration and bring the plant closer to a bright source or provide artificial lighting.
