Plants have low energy needs as compared to animals. Explain.
All the movements in plants are cellular. Plants do not move physically as humans or animals. Sclerenchyma is the tissue which makes the plant hard and stiff. It is known as a supporting tissue. They provide strength to the plant making energy requirements low for the plant.
On the other hand, animals require more energy because they need to move from one place to another for food, shelter, mating etc.
