1. Lesson 27 What are the parts of a flower?

2. A botanical garden is a place where you can see many different kinds of plants and many beautiful flowers. Not all plants have flowers.

3. In the plants that do have flowers, the flower is the organ of sexual reproduction. A flower makes a plant’s sex cells, or gametes.

4. Male and female gametes join to produce seeds. Each seed may grow into a new plant. What may grow if we plant these seeds? What may grow if we plant these seeds?

5. Like the human body, flowers are made of different parts, called organs. The organs and their jobs are:

6. Sepal– leaves found at the bottom of the flower, they protect the flower bud. Petals – colorful leaves that protect the reproductive organs.

7. Stamen – are the male reproductive organs. They make pollen. Most flowers have many stamen.

8. The stamen are made of two parts. Anther – is the top part of the stamen, where the pollen is made. Filament – holds up the anther.

10. Pistil – is the female organ of the flower. It makes eggs. The pistil has many parts.

11. Ovary is the bulging part of the pistil. Ovules – inside the ovary, they house the eggs. Fertilization takes place here.

13. The pollen reaches the egg in the ovary. What should the egg become?
