Plant Growth
Plant growth is how plants get bigger by making new cells using water, light, and nutrients from the soil.
Think of it this way
A small clay pot sits on a kitchen counter with damp soil and a bean seed inside. Each day, you add water and set it near the window for light. Over a few days, a tiny green shoot pokes up through the soil and grows taller. The seed uses water, light, and food from the soil to build new parts — the same way all plants grow.
Explaining plant growth by grade level
Plants need water, light, and good soil to grow tall. Rain that is too sour can hurt them. In one test, sunflowers grew best with normal water. The ones that got sour water did not grow as well.
