Parts of a Flower and Their Functions

The sole purpose of flowers is sexual reproduction, therefore ensuring the survival of the species. Many flowers that rely on pollinators, such as birds and butterflies, have evolved to have brightly colored petals and appealing scents as a way to attract the attention of the pollinators. Flowers that are pollinated by the wind do not need to be as showy in order to survive and, therefore, wind-pollinated flowers are typically duller in both aesthetics and scent. Although all flowers are different, they have several things in common that make up their basic anatomy. The four main parts of a flower are the petals, sepals, stamen, and carpel sometimes known as a pistil. If a flower has all four of these key parts, it is considered to be a complete flower.

The Structure and Functions of Flowers

Flower , the characteristic reproductive structure of angiosperms. In their range of colour, size, form, and anatomical arrangement, flowers present a seemingly endless variety of combinations. They range in size from minute blossoms to giant blooms. In some plants, such as poppy , magnolia , tulip , and petunia , each flower is relatively large and showy and is produced singly, while in other plants, such as aster , snapdragon , and lilac , the individual flowers may be very small and are borne in a distinctive cluster known as an inflorescence. Regardless of their variety, all flowers have a uniform function, the reproduction of the species through the production of seed. Basically, each flower consists of a floral axis upon which are borne the essential organs of reproduction stamens and pistils and usually accessory organs sepals and petals ; the latter may serve to both attract pollinating insects and protect the essential organs. The floral axis is a greatly modified stem; unlike vegetative stems, which bear leaves , it is usually contracted, so that the parts of the flower are crowded together on the stem tip, the receptacle.

Male part Stamen The stamen has two parts Anthers Pollen producing part Filaments They hold up the anthers Female part Pistil The pistil has three parts Stigma Sticky surface at the pistils top, where the pollen germinates Style Holds up the stigma Ovary Contains the ovules o Ovules Become the seed after fertilization by pollen Other Parts of the Flower Petals Usually bright, to attract pollinators Sepals Protect the flower bud when it is developing Receptacle Portion of the stalk with the flower structure Peduncle Flower stalk.

Pollination

A flower , sometimes known as a bloom or blossom , is the reproductive structure found in flowering plants plants of the division Magnoliophyta , also called angiosperms. The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing fusion of sperm and eggs from different individuals in a population resulting from cross pollination or allow selfing fusion of sperm and egg from the same flower when self pollination occurs. Pollination have two types which is self-pollination and cross-pollination. Self-pollination happens when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

Flowers come in many different textures, shapes, colors and sizes. In fact, you can even find ones that you can eat at your local grocery store, which makes it fun to learn about the different parts of the flower!
