What symptom indicates the action of pigment inhibitors on plants?

• A. Leaves turning green
• B. Leaves turning white or translucent
• C. Roots becoming thicker
• D. Stems growing taller

Answer: (B)

The action of pigment inhibitors on plants is primarily indicated by leaves turning white or translucent. Pigment inhibitors work by disrupting the synthesis of chlorophyll and other pigments necessary for plants’ photosynthesis and coloration. When these inhibitors are applied, they prevent the plant from producing chlorophyll, causing the leaves to lose their green color and become paler, often appearing white or translucent. This symptom showcases the direct effect of the inhibitor on the plant's ability to perform photosynthesis and maintain its natural pigmentation. In contrast, leaves turning green would suggest the normal production of chlorophyll, which is contrary to the effects of pigment inhibitors. Similarly, thicker roots or taller stems are not indicative of the action of pigment inhibitors; rather, they could be responses to other growth or developmental factors unrelated to pigment production.
