Parts of a flower

In this article we are going to refresh you everything there is to know about the flower as an important part of a plant, its functions, characteristics, etc., so do not miss this interesting article.

The flower is the reproductive system of a plant whose function is to produce the seeds that guarantee the new generations of plants and through these the continuity of a species and its propagation is given.

What are the parts of a flower?

the petals are part of a flower

They consist of four organs, two essential which are the androecium and gynoecium and two accessories that are the calyx and corolla.

The common thing is to see how the flower is held on a floral peduncle that expands to shape a receptacle where the 4 organs of the flower that we just mentioned are inserted. The flower can be presented as one or together with others in the form of a bouquet.

Chalice

It is made up of the sepals that are generally green, depending on the flower these are arranged separately or glued to each otherLikewise, its shape can be the same or regular, different or irregular.

Corolla

Or petals, are arranged around the flower as a protection Of this, they are usually colorful but they can also be green, all this will depend on the plant. The petals are presented in different ways, well separated, glued, of different sizes, with different shapes and they have a very important function that is emanate the characteristic aromas of each plant to attract insects and promote the pollination process.

Androecium

It is the set of stamens that a flower has, which are in turn the male reproductive organ of the plant. Its parts are the filament and the anther, the latter consists of two pollen sacs which is where the pollen grains are formed.

Gynecium

the gynoecium is part of the flower

It is the central part of the flower and is the female organ of this, it is made up of several leaves called carpels, the ovary that is inserted in the receptacle and contains the ovules, the style of cylindrical shape and containing a spongy tissue and the stigma who is in charge of generate sugary liquids that nourish pollen.

We can conclude that the sexual elements of a plant are:

Ovule

It is composed in its interior by the nucela and a peduncle that join it to the placenta, being the female sexual element.

The pollen

Male sexual element, it is a very fine powder that is generated in pollen sacs whose color can vary from yellow to other shades.

Pollination process

It is the direct or indirect process where the transfer of pollen from the anther to the stigma is generated. It is said that it is direct when the pollination process occurs in the same flower, for that to be possible it must be hermaphrodite.

It is indirect when the pollen of a flower reaches the stigma of another of the same species, this is due to the intervention of external agents and it is the one that occurs more frequently.

These external agents are:

Wind

It is carried from one plant to another due to its lightness, this process is called anemophilia.

The insects

insects pollinate the flower

specifically butterflies and bees that are attracted by the aromas that certain flowers emit, they land on them to obtain their nectar and their body and legs are impregnated with pollen grains which they carry and deposit in others. This is called entomophilia.

The birds

They act like insects, carrying pollen from one flower to another. It is called Ornithophilia.

Water

Flowers that float in water when they collide with each other transmit pollen. It is called Hydrophilicity.

The man

It does it artificially for the study of plants or to generate controlled crops, new varieties of plants or to guarantee reproduction.
