IBPS Clerk Vacancy 2023: Check Total Openings
May 13, 2024Since ancient times, flowers have had a deep connection with human beings. They express happiness, grief, and celebration of human beings. A flower is the reproductive part of a plant. These flowers are not only involved in reproduction but are also a source of food for other living organisms. Flowers are also a rich source of nectar. A flower’s biological function is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Check out the article to learn more about the flower, its function, pollination and more.
Generally, the structure of the flower includes four whorls calyx, corolla, androecium and gynoecium. Based on the presence or absence of one or more floral whorls, flowers can be classified into two types:
Based on the presence or absence of the male and female reproductive parts, flowers can be classified as:
Flowers have four main components: sepals, petals, carpels, and stamens. A complete flower consists of two different parts: the vegetative and reproductive parts.
A flower’s vegetative parts include the following:
The number of petals, sepals, stamens and pistils varies in different plants. The presence of these components distinguishes the flower as complete or incomplete. A flower also has reproductive parts, which are the stamen and pistil. A flower may be composed entirely of female parts, entirely of male parts, or entirely of both.
A flower’s reproductive parts include the following:
Following are the important functions of a flower:
Pollination is the process by which pollen grains are extracted from an anther, the male part of a flower, and transferred to the stigma, the female part of the flower. Pollen grains must be transferred from the same species of flower for pollination to be successful. All plants having flowers depends on the pollination method for reproduction. The two types of pollination are self-pollination and cross-pollination.
The pollination begins when the pollen grains from the respective flowers land on the stigma and form a pollen tube with a style length that connects both the stigma and ovary. After the completion of the pollen tube, the pollen grain begins to transmit sperm cells from the grain to the ovary. Later, when the sperm cells reach the ovary and egg cells, the process of fertilisation in plants will begin. The seed is then released from the parent plant, allowing it to grow into a plant and continue the reproductive cycle via pollination.
