Poinsettias and Christmas trees help to make our homes beautiful during the holidays. But plants do much more than just add to our festive decorations. They are essential to the survival of all life on Earth. Plants provide the oxygen that we breathe. In fact, scientists call the rain forests the "lungs of the Earth." Plants are also a vital part of the food chain and a source of everything from building materials to medicines. To learn more about plants, use the direct links on The Times Launch Point Web site:
Here are the best sites for getting your schoolwork done or for just having fun.
Why Do Plants Have Flowers? Find out how plants pollinate and produce flowers. Take a close look at the inside of a flower and learn the name and function of each part.
