Structure of pistil

The female component of a flower is made up of stigma, style, ovary, and ovule, which are all found in a pistil. Pollination and fertilisation were developed or adapted largely for pollination. Sperm is deposited for fertilisation with the ovules in the ovary when the pollen tube (style tissues) grows. The pistil, in general, is a collection of male gametes from the androecium, the male reproductive portion of the female reproductive system. 

Parts of a pistil:

A flower’s pistil is usually found in the centre, surrounded by stamen. The stigma, style, and ovary are the three primary components. 

1. 1. Stigma: The pistil stigma is sticky and positioned at the top of the pistil. Its function is to trap pollen grains on the pistil, allowing pollination to occur. 
   2. Style: The style is a stalk-like tube that extends from the pistil’s ovary. Its job is to deliver the male gamete from the sperm to the ovary.

• Ovary: The female gamete, the ovules, are found in the ovary of the pistil. The ovary’s job is to keep the ovules safe. This occurs after the ovules have been fertilised and the ovaries’ walls have thickened. 

Structure of pistil:

The female reproductive portion of a flower is the pistil, which is located in the centre of the bloom. A swelling base, the ovary, ovules, a stalk, a pollen-receptive tip, the stigma, and other female reproductive elements of a flower make up the majority of it. It has a variety of shapes and is frequently sticky. The number of pistils in a flower varies depending on the species. Each pistil is made up of one to many enrolled leaf-like appendages that serve to protect the ovules. 

Functions of pistil:

1. It is a flower’s female reproductive component.
2. It collects pollen and assists with pollination.
3. It is also involved in the pollen grain germination process.
4. It also contributes to pollination by transporting pollen grains.
5. The stigma, which has a sticky tip and is important for pollen grain germination, is part of the pistil. 

Ovary of a flower:

The ovary is a highly important element of the female reproductive organ that is present in the flower in some flowering plants. It is that region of the pistil that tends to hold all of the ovules. The ovary is attached to the sepals and petals and is either below or above the connecting point. The mature ovary, to be precise, produces the fruit or seeds that grow on the plant. 

Structure of ovary:

The ovary is a vital component of the pistil, as it houses the majority of the ovules or eggs. The plant’s petals and sepals are tied to the site. In most plants, the pistil is made up of one or more carpels fused together, which is known as tricarpel or bicarpel. As a result, depending on the number, the ovary may only contain certain parts of the carpel. 

The stigma and style of the plant are located just above the ovary and are where pollen grain collecting and germination take place. The pollen grains grow in the stigma and then pass through the style to the plant’s ovary with little difficulty.

Functions of the ovary:

One of the most important jobs of the ovaries is to keep the delicate ovules safe in the protective chamber so that they can develop into seeds and grow. 

One of the most important roles of the ovaries is to ensure that the fertilised seeds are transported properly. The ovules will develop into seeds once they have been formed and fertilised. The ovary’s job is to transfer these fully developed seeds safely to ensure that they germinate properly. After the fertilisation process is completed and the zygote is formed, the ovules in the ovary will convert into seeds. This will result in the formation of the embryo, which the ovary will assist in keeping safe. 

Conclusion:

An ovary’s job is to prepare ovules for fertilisation, preserve growing zygotes, and mature into a seed-bearing fruit. The walls of the ovary thicken and grow thicker after fertilisation and as the seeds mature. The ripened fruit may develop from the ovary or other sections of the flower, such as the perianth, depending on the flower type.
