Plants cannot grow without soil.
Plants cannot grow without soil.
The correct option is B - False
Plants need water, sunlight, carbon dioxide, and mineral nutrients to grow. Normally, they get water when it rains or you water them. Sunlight is provided from the sky or from special types of artificial lights. Carbon dioxide is in the air we breathe. And mineral nutrients needed by plants are often naturally present in the soil, but they are also in fertilizers.
The soil itself is not really needed by the plants - just the nutrients and water in it. So if the nutrients are put in water, the plants can get what they need to grow without the soil. For example, hydroponic is a technique of growing plants using solutions rich in mineral nutrients without soil. Terrestrial flora could be grown with their roots in the mineral solution only, or in an inert medium like gravel or perlite. The nutrients in hydroponics could be obtained from duck manure, fish waste and from normal nutrients.
