They help plants grow by carrying pollen from one flower to another. This process is called pollination. Without pollination, many plants cannot make fruit or seeds. A bee has special hair on its body that collects pollen. When it lands on a flower, pollen sticks to its hair. Then, when the bee flies to another flower, some of the pollen falls off. This helps the new flower make seeds. Bees live in groups called hives. Each hive has a queen bee, worker bees, and drone bees. Worker bees are the ones that collect pollen and make honey. They visit hundreds of flowers every day. Bees are important to humans too. Many of the fruits and vegetables we eat, like apples and tomatoes, need bees to pollinate them. Without bees, we would have fewer foods to eat. We must protect bees and their homes. （ ）1. What do bees carry from flower to flower? A. Fruit. B. Seeds. C. Pollen. D. Honey. （ ）2. What is pollination? A. Making honey. B. Carrying pollen between flowers. C. Building hives. D. Eating fruits. （ ）3. What do worker bees do? A. They are queens. B. They collect pollen and make honey. C. They eat fruit. D. They fly away from the hive. （ ）4. Why are bees important to humans? A. They make honey. B. They build hives. C. They help grow fruits and vegetables. D. They are small insects. （ ）5. What would happen without bees? A. We would have more food. B. We would have fewer foods. C. Flowers would grow better. D.
