Plants provide oxygen, which is the air we breathe. Plants also provide wild animals with food and shelter. Humans eat many plant parts such as strawberries and lettuce.

Plants grow from seeds.

When a seed receives water and sunlight, it grows into a healthy plant. A small plant can grow in a few months, but a big tree can take many years to fully grow.

Plants need time to grow.

Just like people, plants need time to grow. Once a seed grows its roots, it will then start growing a stem, leaves and sometimes flowers.

QUESTIONS ABOUT PLANTS

What do all plants need to grow?

All plants need water and sunlight to grow.

How can a plant grow without soil?

It can still grow as long as it receives water and sunlight. The roots of a plant help it stand up straight and help the plant take in water from the ground. As long as the plant gets water from the roots and sunlight, it can grow.

Why would it not be okay to keep a plant in a dark place?

If a plant was kept in a dark place, it would not get sunlight. Without sunlight, the plant could not grow.

Can a plant grow if it has sunlight, but no water?

No. Plants need both sunlight and water to grow.

Do plants grow fast or slow?

Seeds begin growing when they are planted, but it can take a few days or weeks before we can see a plant forming. For a small plant to grow it can take months and for a tree to fully grow it can take years.

What happens if a plant receives too much water?

Too much water can stop a plant from growing. Some plants need more water than others, and some need more sunlight than others. When taking care of a plant, it is important to know the best conditions to keep the plant healthy.
