In soil drenching, the pesticide is absorbed by which part of the plant?

Explanation:
In soil drenching, the plant takes up the pesticide through the roots. Placing the chemical in the soil around the root zone means it encounters the root surfaces first, where it is absorbed by root hairs and the surrounding epidermis. From there, many pesticides move upward with the water stream through the xylem to above‑ground tissues such as stems and leaves, which is why soil-applied products can have systemic or extended effects. Leaves, stems, and flowers aren’t the entry points for a soil drench; they’re reached after uptake via the roots and subsequent transport inside the plant.
