There are thousands of types of plants that grow throughout the world. Humans use plants for many things like food, energy, and clothing.
Plants turn carbon dioxide from the air into energy and release oxygen, which humans need to breath. Plants need water to grow and get energy from the sun.
Plant roots absorb water and nutrients from the soil; leaves collect energy from the sun. Water and energy are stored in the stem of most plants.
Plants are an important source of food; humans have also used plants as medicine. Wood and plant fibers are used in houses, books, and clothing.
Some plants have harmful pollen and some berries can be poisonous. Invasive places harm native plants.
First Nations and other native groups have great respect for plants. Many places have official trees and flowers, like the maple leaf for Canada.
