What Plants Need

Plants like people, need food and drink for survival, growth, and reproduction. The manufacture their food by means of a process called photosynthesis, from elements they find in the air, water, and soil. Sunlight provides the energy for this activity, which is in reality a chain of chemical reactions. Plants also make their own vitamins and digestive enzymes, and the hormones that govern their desires, which are called tropisms. Working with plants gives you a great respect for them. Plants can absorb nutrients through their leaves as well. Plants reproduce in different ways, one of them by means of seeds.
