Plants are living things even though they do not walk, talk, or eat like animals. Plants grow, need water and sunlight, respond to their surroundings, and make new plants through seeds. They are alive in their own quiet way.
Plant a seed in a cup and watch it grow over several days. Compare it to a plastic flower that never changes. Draw the real plant at different stages and talk about what makes it alive.
When you think of living things, you probably picture animals first — dogs running, birds flying, fish swimming. But look at the tree outside your window. Look at the grass in your yard. Those are alive too! Plants are living things, just like animals.
Plants do not move from place to place, and they do not make sounds. That can make them seem more like rocks or chairs than like cats or dogs. But watch a plant closely over a few days or weeks, and you will see it grow. A tiny seed sprouts into a stem. Leaves unfold. A flower blooms. That kind of change is something only living things do.
Plants also have needs, just like you do. They need water, which they soak up through their roots. They need sunlight, which they catch with their leaves. They even need air. If you stop watering a plant, it wilts and dies — just like an animal that does not get food and water. Having needs and being able to die are signs that something is alive.
Finally, plants can make more of themselves. A sunflower makes seeds. Those seeds fall into the ground and grow into new sunflowers. An apple tree grows apples, and inside each apple are seeds for new trees. This is how plants keep going, generation after generation — the same way animals have babies.
