Detailed explanation-1: -A student placed a potted plant growing in a glass pot horizontally (with the root and shoot, both being in the horizontal direction). After a few days, the student observed that the root of the plant bends downwards and the shoot (stem) of the plant bends upwards.
Detailed explanation-2: -Root is a part of a plant which is present below the ground. Except for roots, all the parts of a plant like flowers, leaves and fruits grow on stems.
Detailed explanation-3: -Growing potted plants lets you skip the dirty work of weeding and clearing a soil bed. Start by providing the light and soil conditions that your specific plants prefer. When you’re ready to plant, nestle your plants into the pot, and soak the soil to help them settle into their new home.
