1. What are Weeds?
Undesirable plants growing in the wrong place without being planted are known as weeds. For example, small grass-like leaves grow in the cracks of sidewalks, in gardens, parks, and lawns. These plants are unwanted because they self-grow and steal the nutrition of the plants beside which they are growing.
