　　Flowering Plants

　　What arc the parts of a flower?

　　Flowers can have male parts and female parts. The female parts make eggs that

　　become seeds. The male parts make pollen. Pollen is a powdery material that is

　　needed by the eggs to make seeds. To make seeds, pollen and eggs must come

　　together. The wind, insects, and birds bring pollen to eggs. Many animals love

　　flowers\' bright colors. They also like a sugary liquid in flowers. This is

　　called nectar. While they drink nectar, pollen rubs off on their bodies. As they

　　move, some of this pollen gets delivered to the female flower parts.

　　Over time, the female parts turn into fruits that contain seeds. Animals

　　often eat the fruits and the seeds pass through their bodies as waste. The

　　animals do not know they are working for the plants by planting seeds as they

　　travel to different places! (147 words)

　　Living Things React

　　You and all organisms live in an environment. An environment is made up of

　　everything that surrounds an organism. It can include the air, the water, the

　　soil, and even other organisms.

　　An organism responds to changes in its environment. When an organism responds

　　to a change, it reacts in certain ways. All living things respond in someway.

　　Have you ever noticed how plants and insects respond to light? Plants bend

　　toward light. Insects fly toward light.

　　Living things also respond in other ways. The leaves on some trees respond to

　　a change in season. In autumn, they change colors and then fall off the branches.

　　Animals also respond to a change in season. Squirrels save nuts for the winter.

　　Bears sleep through the winter in a cave.

　　cold. What other ways do you respond to changes in your environment? (156 words)
