What is the purpose of the stigma in a flowering plant?

The stigma is an important part of a flowering plant's reproductive system. Its main purpose is to receive and recognize pollen, which is necessary for fertilization and the production of seeds. When a flower is ready for pollination, the stigma is typically sticky or has hairs to help trap and hold onto pollen grains.

To find the purpose of the stigma in a flowering plant, you can search for information on plant reproduction and specifically the role of the stigma. Some reputable sources for your research can include botanical textbooks, scientific articles, or educational websites from botanical or horticultural organizations. These sources will provide detailed explanations on various parts of a flower and specifically discuss the stigma's functions within the process of pollination and fertilization. Reading and learning from multiple sources can give you a comprehensive understanding of the topic.

The stigma is a key part of the reproductive structure of a flowering plant. Its purpose is to receive and recognize pollen grains, which contain the male gametes (sperm cells) needed for fertilization. The stigma is located at the top of the pistil, which is the female reproductive organ of the flower.

Once the pollen lands on the stigma, it starts to germinate and form a pollen tube that grows down through the style (a long, slender tube connecting the stigma and the ovary) towards the ovules contained within the ovary. This process allows the pollen grains to deliver their sperm cells to the ovules for fertilization to occur. In essence, the stigma serves as the landing site for pollen to initiate the fertilization process, leading to the development of seeds and fruits.
