31. Most flowers, like the ones in the
pictures on this page, have four parts. Notice
the flower buds. The green parts of flower
bud are the sepals. They cover and protect
the flower growing inside. As the flower
grows, it forces the sepals apart. The bud
opens into a beautiful flower.
When you look at a flower, you probably
notice the petals first. The petals are the
colorful parts of the flower. The petals attract
bees, butterflies, birds, and other living
things.
32. Notice the five small, knoblike structures
in the center of the ring of petals. These
structure make up the pistil is the part of the
flower that make eggs. The eggs will grow
into seeds when they are combined with
sperm in pollen.
Now look just below the pistil. You can
see the cluster of stamens with rounded tips.
The stamens make tiny grains of pollen at
their tips. A flower needs sperm in pollen to
combine with the flower’s egg to make seeds.
