Anatomy of a Flower

Petal

The petals are the essential food producers for the entire plant. The nutrients and minerals are absorbed by the roots and then carried to the leaves by the stem. The leaves then use the chlorophyll, which is the green pigment in the petals, and a process called photosynthesis to use the energy from sunlight to create a glucose that feeds the plant. The leaves also release oxygen into the air, which animals need.

Anatomy of a Flower

The Style allows the pollen to pass to the ovary and join with an ovule. The Style connects stigma to the ovary and provides necessary stimulus for the growth of pollen tubeThe Stigma is the part of the pistil where pollen germinates.

Learn about the different parts of a flower and the role they play in plant reproduction.

Stigma & Style

While the roots absorb the minerals and moisture from the soil, the stem carries those minerals and water up to the top of the plant. Some may be flexible while some will be fixed and even hard, like a tree trunk. The stem is one of the hardest working parts of the plant.

Stem

Sepal

One of the usually separate, green parts that surround and protect the flower bud and extend from the base of a flower after it has opened. Sepals tend to occur in the same number as the petals and to be centered over the petal divisions.

Ovary, Ovules, Anther, & Filament

The female reproductive organs are the pistil and include the stigma, style and ovary.The male reproductive organs are called the stamen and are made up of the anther and filament.

Receptacle

The Receptacle is the area at the apex of a stem that bears the organs of a flower or the florets of a flower head
