Parts of the Flower

Flowers are a fundamental and specialized part of plants. They are in charge of carrying out their sexual reproduction, from which the seeds that will give life to the next plants of the same species arise.

They are characterized by being a stem with determined growth, whose leaves are responsible for the production of gametes. The more specialized flowers have a short growing period.

Most of the plants produce flowers and are called as spermatophytes. These spermatophytes are differentiated into two groups:

  • gymnosperms: plants that have flowers that are gathered in reproductive or fertile leaves known as strobili.
  • Angiosperms: They are the plants that have a typical flower that can even reproduce fruits with seeds. They are the most advanced and predominant plants on Earth.

The flowers have a delicate structure that begins in the stem of the plant and from there the other parts develop. Although there are thousands of types of flowers, they all share parts that are essential for their growth, pollination and reproduction.

Parts of the flower


The peduncle is the last part of the stem that supports the flower, which widens or dilates at its end, giving shape to the receptacle. It is where the modified and specialized leaves of the flowers responsible for their reproduction are inserted.


The receptacle or floral axis is the part that follows the peduncle, since it is its widening and where the leaves of the flower and the rest of its parts settle.


The floral envelope is called perianth, that is, the leaves that protect and surround the reproductive organs of the flower. In the perianth are the sterile whorls of the flower: the calyx and the corolla. In this way it protects the reproductive organs of the flowers in their development process.

Once this stage is complete, the perianth takes on a striking color to attract pollinating animals.

  • Chalice: It is a structure composed of sepals, which are similar to leaves and green in color. Its function is to protect and support the petals of the flower when it is still a bud.
  • Corolla: It is the part made up of the colorful and striking petals or anthophiles of the flower in order to attract pollinating animals. The corolla gives shape to the flower and is generated after the sepals.


The carpel forms the female reproductive part of the flower. The set of carpels forms the gynoecium, which may contain one or more pistils.


The pistil refers to the units of the female organ of the flower that contains the style, stigma and ovaries, which together make up the carpel.


Gynoecium is the female reproductive system of the flower. It is formed by one or several green leaves or carpels united or separated through a pistil, on which the ovaries that contain the female gametes are produced. The gynoecium is composed of the following elements:

  • Style: cylindrical and tubular structure that serves to store and conduct the pollen.
  • Stigma: is the top of the pistil. Its function is to make the sticky nectar necessary for pollen.
  • Ovary: It is located in the lower part of the pistil formed by one or more carpelar leaves. It contains the ovules that will be fertilized by male pollen.


The male reproductive apparatus of the flower is called androecium, composed of the following parts:

  • Stamen: It is the male organ that develops in flowers and where pollen is produced.
  • Anther: terminal part of the stamen of flowers, where pollen production takes place.
  • Filament: it is the part that supports the anther, it is also the sterile part of the stamen. It can vary in size and shape depending on the type of flower.
  • Teaks: This is where the pollen grains are found.

The petals vary according to the type of flower and its colors, which in addition to attracting pollinating animals, also attract people’s eyes.
