Orchids are a diverse family of flowering plants known as Orchidaceae. They are characterized by their unique and intricate flowers, which come in various shapes, sizes, and colors. There are over 25,000 species of orchids, making them one of the largest plant families in the world. Orchids can be found in almost every habitat except for extreme deserts and polar regions. These plants are often epiphytic, meaning they grow on other plants for support, but they can also be terrestrial. Orchids have specialized structures called pollinia that help in the transfer of pollen, ensuring successful reproduction. Many orchids are popular in horticulture and are cultivated for their beauty and variety.
