Draw a labelled diagram of the longitudinal section of a flower.

A longitudinal section of a flower is a cut that is made along the length of the flower, allowing you to see the different parts of the flower.

The main parts of a flower that can be seen in a longitudinal section are:

1. The ovary: This is located at the base of the flower and contains the ovules, or immature seeds. It will develop into the fruit after fertilization.
2. The style: This is a stalk that connects the ovary to the stigma, which is the receptive part of the pistil.
3. The stamen: This is the male reproductive organ of the flower, and it consists of the anther, which produces pollen, and the filament, which supports the anther.
4. The petals: These are the colorful and usually fragrant leaves that surround the reproductive organs and are often the most visible part of the flower.
5. The sepals: These are the small green leaves that are located at the base of the petals and protect the bud before it blooms.

In summary, a longitudinal section of a flower would show the Ovary, Style, Stamen, Petals and Sepals.
