Sample passage and quiz from Parts of a Flower

A flower is the part of a plant that makes seeds. Flowers are important because seeds grow into new plants. Without flowers, many plants could not reproduce.

The outside of a flower has colorful petals. Petals are the bright parts that attract animals like bees and butterflies. These animals are called pollinators because they help move pollen from one flower to another. Pollen is a powdery substance that flowers need to make seeds. Petals use bright colors and sweet scents to get pollinators to visit.

Below the petals are small green parts called sepals. Sepals protect the flower bud before it opens, like a cover protects a book. Once the flower opens, the sepals stay at the base.

Inside the flower are the parts that make seeds. The stamen is the male part that makes pollen. It looks like a thin stalk with a small knob on top. The pistil is the female part in the center of the flower. When pollen from the stamen reaches the pistil, the flower can make seeds. These seeds will eventually grow into new plants.

Each part of a flower has a special job that helps the plant reproduce and continue its life cycle.

Interesting Fact: The largest flower in the world is the Rafflesia, which can grow up to three feet wide and smells like rotting meat to attract flies as pollinators!
