How to Label Seed-Producing Parts of a Flower


It is rather helpful to have an understanding of flowers and the different parts that are involved in producing seeds. Each part plays a role in the development of the seeds and you will need to know what they are if you are planning on trying some hand pollination.

Structural Parts

Step 1

The "perianth" is the outer part of the flower. Look at the flower and notice the most obvious parts, such as the petals or the corolla. Draw a simple outline of the petals as you see them. The perianth attracts pollinators such as bees and butterflies. It is brightly colored and usually velvety soft.

Step 2

Draw in the part of the stem that is holding the petals and label it as the "pedicel." The pedicel provides support for the flower, and also distributes water and nutrients to the flower.

Step 3

Don't forget the little, usually green leaves just below the petals. Those leaves form the "calyx" and each is called a "sepal." Before the flower opened, the sepals covered the blossom.

Reproductive Parts

Step 1

Look for the tallest structure sticking out of the flower. That is typically the "male" reproductive part, or the "stamen," which is actually made up of two parts. You can label the little bulb on the end of it as the "anther" and the stem holding it as the "filament." The anther contains the pollen from the flower, which will cling to the feet of the bees as they buzz around the flower and be deposited in other flowers.

Step 2

Notice the flower also has a single "carpel" in the middle (if it is a perfect flower). The carpel is the female portion of the flower and the very top is called the "stigma." That is where the pollen is deposited.

Step 3

Find the neck of the carpel just below the stigma. The pollen will travel down the neck of the ovule, which is called the "style," and down into the ovum or the fat part within the flower. That is where the seeds will be fertilized from the pollen and be stored until they are ripe.

Finish the Labeling

Step 1

Draw lines to the different parts of the flower you have labeled. Use a ruler to draw straight lines to the parts of the flower. Some of the parts are related, such as the anther and the stamen. Connect the lines to those parts with a vertical line on the outside edge.

Step 2

If desired, add a little color to the different parts of the drawing to differentiate the different parts from one another. You can simply copy the colors as you see them on your flower.

Step 3

List each of the parts that you labeled and write a brief description of each one as described in the text above.
