Plants need light to make food. That's why plants grow from inside the dark earth up toward the light. When they reach light, a plant's leaves open. Then the plant uses the light to make all the good things it needs to grow.
Growing up
Maybe you've got a green thumb. Collect some seeds or beans. Put some soil in a pot and plant the seeds or beans. If they have enough light, air, and water, they should grow.
Growing down
There is one part of a plant that doesn't grow up, and that is the roots. They grow down. Their job is to hold the plant in the ground and to pull water, and food, up through the soil.
Starting seedy facts
