The parts of a flower with diagrams

The parts of a flower can be broken up into the pistil (stigma, style and ovary) and stamens (anthers and filament), petals, sepals, ovules, vessel and stem. Below, we'll go into each part and pick up some great flower diagrams to learn from.

As simple as it may seem, flowers have extremely complex structures with many different parts. If you want to learn about all of the different parts of a flower using diagrams, you have come to the right place.

In this article we are going to discuss all the different parts of a flower and see where they are and what they look like with diagrams.

What is a flower

Before we get into the different parts of a flower, however, we need to understand what a flower is.

Flowers are the reproductive organs of magnoliophytes (sometimes called angiosperms). Magnoliophytes are what are commonly known as flowering plants. Flowers are also sometimes referred to as blossoms or blossoms.

Flowers, blossoms and blossoms have a very specific biological function. They were designed to influence reproduction. How do you do that? Usually they provide the mechanism to unite fused sperm with eggs, either by facilitating the fusion of eggs with sperm from different flowers (this is called outcrossing) or by allowing the egg and sperm from the same flower to fuse (this is known as Self-fertilization).

But is it necessary that flowers should be so easy to the eye? In an important sense, yes. Being attractive to some animals helps with fertilization as these animals are used as vectors to transmit pollen.

Of course, most people are not interested in thinking about the reproductive biological function of flowers in flowering plants. Flowers are admired for their beauty and that is why they have played an important role in human culture, religion, poetry, romance, medicine and various rituals for millennia.

A flower cannot bloom without sunshine, and man cannot live without love. - Max Muller

The parts of the flower

The parts of a flower can be divided into two different parts: the vegetative part and the reproductive (or sexual) parts.

The vegetative part consists of the petals and the structures in the flower envelope.

Most flowers have four different types of structures, all of which are attached to the tip of a stem. All of these parts are arranged in a whorl.

Here are the four main whorls, from the base:

  • The perianth is the non-reproductive part of the flower. It is formed by the chalice and the crown. The chalice is the outermost whorl. Each of the units that correspond to the chalice is known as a chalice. Sepals tend to be green. While the flower is in the bud, the calyx encloses the rest. Not all flowers have a calyx, others have them quite prominently, and yet for the third group the calyx can be like a petal. The corolla is the nearest whorl and it is towards the tip. There the petals are in the bloom. Petals are usually soft, thin, and have attractive colors that are attractive to animals. This is the key to the pollination process.
  • The reproductive part of the flower consists of two vertebrae: the androecium and the gynoeceum. The androecium is the next world from the petals. It takes its name from the Greek Andros Oikia which means "house of man". The aroecium consists of stamens consisting of a filament (stem) and an anthers on which pollen is produced and distributed. The last diaper is the gynoeceum, which is the innermost part of a flower. It takes its name from the Greek Gynaikos Oikia, which means "house of the woman". The gynoeceum has one or more units known as carpels. What are carpels? A carpel (or several fused carpels) forms an ovary, that is, the hollow structure that internally forms the ovules.

How do flower plants reproduce?

The ovaries that are produced in the ovary are megasporangia. They produce megaspores through a process known as meiosis. The megaspores then become female gametophytes that produce egg cells.

Another way to look at the gynoeceum is to think of it as a stamp made up of three parts:

  • One ovary.
  • One style.
  • A stigma.

The pistil has a carpel or several carpels that have grown together. The style is the supportive stem where the pollen tubes extend from the pollen grains to the tip of the pistil, known as the stigma. The stigma is the receptor of pollen.

Do all flowers have the same structure?

It would be a mistake to assume that all flowers have exactly the same structure. So far we've looked at the most typical structure, but there are many species of plants that have different structures than the one I described.

No matter what the structure of the flower is, all of its parts are defined according to the same criterion: their position. The parts of a flower, however many, are never defined by their function. What does that mean? It means that when a flower plant species lacks a certain part in its structure, the function that part performs in plants that have it is performed by another part. Some flower plants have different parts fused together. Others barely have petals and instead the sepals feel and feel like petals (this is the case with the floral plant family known as the Ranunculaceae).

In this article we have given you a very general idea of ​​the parts of a flower, but if you want more detailed information you will need to study the different families separately, as the structure can vary widely between different families.
