Which term describes plants being killed by herbicides that are absorbed and move throughout the plant?

• A. Translocated Herbicides
• B. Plant Growth Regulator
• C. Systemics
• D. Molluscicide

Answer: (A)

Translocation is the key idea here: some herbicides are absorbed by the plant and then moved through the vascular system to distant tissues, including growing points. When an herbicide travels inside the plant like this, it can disrupt essential processes at multiple sites, causing the entire plant to die rather than just the treated tissue. The term that captures this moving, internal spread of the herbicide is translocated herbicides. Plant growth regulators describe a type of herbicide that affects development, but it doesn’t directly emphasize movement through the plant. Systemics refers to herbs that move within the plant, but the wording here highlights the movement itself as translocation, which is why this term is the best fit. Molluscicide targets mollusks, not plants.
