Which term means growing plants without soil?

• A. Hydroponics
• B. Herbicide
• C. Infiltration
• D. Insecticide

Answer: (A)

Growing plants without soil is called hydroponics. In hydroponics, plants get all their nutrients from a water-based solution, and roots can be kept in air or supported by an inert material like rock wool or perlite. This setup lets you control exactly what nutrients and pH the plants receive and can save water, making it useful in places with poor soil or limited space. The other terms refer to different ideas: a herbicide kills weeds, an insecticide kills insects, and infiltration is about water seeping into the soil. So hydroponics is the soil-less method of growing plants.
