The document discusses the parts of flowers, including the pistil, which makes eggs; stamens, which make pollen; petals, which attract bees and birds; and sepals, which protect flower buds. It also covers the structure of sentences using the infinitive and provides vocabulary terms related to plant structures. Examples are given of writing sentences about flower parts and specifying each part in pictures using the vocabulary.

The parts of a flower
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.
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

7. 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.

Example 1:
real flower
Papaya flower has 2 parts. There are stamens and white petals. It
is not complete flower because it doesn’t have pistils. Moreover, it
doesn’t have sepals. Papaya grows from seeds when its egg is
combined with sperm in pollen.
Example 2:

24. real flower
Shoeflower has four parts. It is complete flower because there are
pistils and stamens with pollen. It has many colors of petals such
as pink, red, yellow and white but it’s pink petals in this picture. It
