Pistil, Female Reproductive Organ in Flowering Plants

The pistil is a crucial part of the female reproductive system in flowering plants. It plays an essential role in the process of reproduction by helping in the formation of seeds. Understanding the pistil is important for the NEET exam , as it is a key topic in the chapter on plant reproduction and flowering.

Definition of Pistil

Structure of Pistil

• Stigma: The stigma is the topmost part of the pistil. It is sticky in nature, which helps to trap the pollen grains that are transferred from the male organ (stamen) during pollination. The stigma is essential for receiving pollen and starting the fertilization process.
• Style : The style is a long, tube-like structure that connects the stigma to the ovary. It provides a pathway for the pollen tube to travel from the stigma to the ovary during fertilization. The style is usually slender and elongates after the flower is pollinated.
• Ovary : The ovary is the bottom part of the pistil. It contains ovules, which are the potential seeds. After fertilization occurs, the ovary develops into a fruit, and the ovules inside it grow into seeds.

Function of Pistil

• Pollination: The pistil receives pollen from the male reproductive organ (stamen). This pollen is transferred to the stigma either by wind, insects, or other animals. Without pollination, fertilization cannot occur.
• Fertilization : Once pollen lands on the stigma, it travels down the style and reaches the ovary. Inside the ovary, the sperm cells from the pollen fertilize the ovules, leading to the formation of seeds.
• Seed Formation: After fertilization, the fertilized ovules become seeds, and the ovary develops into a fruit. This process is essential for plant reproduction and survival. The seeds that are formed inside the fruit can grow into new plants.
