Absorption is defined as which of the following?

Absorption is defined as which of the following?

• A. The movement of pesticides in the plants
• B. The rate of environmental contamination
• C. The evaporation of pesticides from leaves
• D. The movement of pesticides in the soil

Answer: (A)

Absorption is the entry of a pesticide into the plant from its surroundings and its initial movement within the plant’s tissues. This is why it’s the best choice: it focuses on the pesticide crossing the plant boundary and becoming part of the plant, enabling it to move inside to reach where it works. The other options describe environmental fate (how contamination develops in the environment), evaporation from leaf surfaces (volatilization), or movement through soil (soil transport), which are separate processes from absorption by the plant. In practice, absorption can happen through roots from the soil or through leaves from foliar applications, after which the chemical may be translocated within the plant.
