六、阅读理解（每小题2分，共10分）
Plants are amazing living things. Each part of a plant has a special job to help it grow well. Let's learn about their roles.
Roots grow under the ground. They not only keep the plant in the soil but also take in water and minerals from the soil. Stems are like the plant's "transportation system". They hold the plant upright and carry water and food between roots and leaves. Leaves are usually green because they have chlorophyll. With sunlight, air and water, leaves make food for the whole plant. Flowers are the most beautiful part of a plant. Their job is to make seeds. After flowers fade, fruit grows. Fruit can protect the seeds and help them spread to new places.
All parts work together. Without any of them, the plant can't grow healthily.
