Which term describes the process of taking in a substance?

• A. Absorption
• B. Adsorption
• C. Leaching
• D. Runoff

Answer: (A)

Taking a substance into the interior of a plant or its tissues is absorption. In turf, this means roots or tissues drawing in water and dissolved nutrients so they become part of the plant’s system. This differs from adsorption, which is the sticking of molecules to a surface (like soil particles) without entering the interior. Leaching describes soluble substances being washed downward through the soil beyond the root zone, while runoff is surface flow that carries materials away from the ground. So, absorption is the process of taking in a substance.
