Which term describes the process where pesticides are taken up by a plant or surface?

• A. Absorption
• B. Adsorption
• C. Volatile
• D. Synergism

Answer: (A)

Absorption is the process by which a pesticide moves from where it’s applied into the plant tissues or into a surface material. In plants, this means the chemical crosses the leaf cuticle or root membranes and becomes part of the plant’s internal system. This is different from adsorption, which is the pesticide binding to surfaces such as leaf waxes or soil particles without being taken into the material. Volatile refers to a substance’s tendency to vaporize and move as a gas, not uptake into tissue, and synergism describes one substance enhancing the effect of another, not uptake. So, absorption best fits the idea of the chemical being taken up by a plant or surface.
