Let's meet Worker No. 55. He wears a green uniform and works in Workshop 1001 in the Leaf. Each workshop has 20 to 100 workers. Their job is to collect sunlight and CO₂ during the day. At the same time, workers from the Root send up water. The water travels up to the Leaf through the Stem. Then the workers in the Leaf mix water, CO₂ and sunlight to make something important. What do they produce? Most importantly, they make sugar! Sugar helps the plant grow strong. Another product is oxygen. The plant doesn't need much oxygen, but it means everything to animals and humans—we need it to breathe! There are millions of plants on Earth. They give us more than food and oxygen. They keep the soil in place, cool the air and provide homes for many animals. Without plants, the natural world would be very different. We should always remember to protect them. ( )1.

Second, plants can live for a very long time. Some plants can grow food for 10,000 years. Third, plants are not just green. There are red, yellow, purple and even blue plants.
