These beautiful blooms are the structures flowering plants use to reproduce. Flowers are made up of four basic parts: the pistil, stamens, sepals, and petals. Four basic parts The eye-catching color of flowers usually comes from the sepals and petals. In some flowers these two parts can be hard to tell apart. The sepals are leaf-like, usually connected at the very base of the flower. They may be green or brightly colored, depending on the plant species. Sepals surround the flower bud, protecting it as it develops. Once the flower opens, the petals are visible. These brightly colored, leaf-like parts attract pollinators. Some even have ultraviolet markings to direct pollinators to the nectar. The pistil of a flower is sometimes called the female reproductive structure. This is because it includes the ovary where seeds (the plant's offspring) develop. Three pieces make up the pistil. A sticky stigma catches pollen. A stalk-like style holds the stigma up in the air. The ovary sits inside the flower at the base of the style. In the ovary are female sex cells: ovules. They contain a half-copy of the plant's genetic code to pass down to its offspring. Most flowers have only one pistil. Some scientists call the stamen of a flower the male reproductive structure. It is made up of two parts: the...

Peduncle:The stalk of a flower. Receptacle:The part of a flower stalk where the parts of the flower are attached. Sepal:The outer parts of the flower (often green and leaf-like) that enclose a developing bud. Petal:The parts of a flower that are often conspicuously colored. Stamen:The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther:The part of the stamen where pollen is produced. Pistil:The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed. Stigma:The part of the pistil where pollen germinates. Ovary:The enlarged basal portion of the pistil where ovules are produced.

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. Here we’ll learn about every part of a flower, and understand in details why flowers are different from one another. Complete vs. Incomplete 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. If any one of these elements is missing, it is an incomplete flower. Incomplete • Holly • Corn • Squash • Grasses Perfect vs. Imperfect The reproductive parts of the flower that are necessary for seed production are the stamen (the male organ) and carpel (the female organ). If a flower has both of these parts, it is called a perfect flower, even if it lacks some of the other key parts. If a flower has only one of the reproductive parts, either a stamen or carpel, it is considered to be an imperfect flower. Imperfect • Begonia • Squash • Cucumber • Corn • Walnut • Chestnut Monoecious ...

Overview A typical flower has four main parts or whorls referred to as the calyx, corolla, androecium, and gynoecium. The outermost whorl of the flower has green, leafy structures known as sepals. The sepals, collectively called the calyx, help to protect the unopened bud. The second whorl is comprised of petals, usually, brightly colored and are collectively called the corolla. The number of sepals and petals varies depending on whether the plant is a monocots, petals usually number three or multiples of three; in dicots, the number of petals is four or five, or multiples of four and five. Together, the calyx and corolla are known as the perianth. The third whorl contains the male reproductive structures and is known as the androecium. The androeciumhas stamens with anthers that contain the microsporangia. The innermost group of structures in the flower is the gynoecium, or the female reproductive component(s). The carpel is the individual unit of the gynoecium and has a stigma, style, and ovary. A flower may have one or multiple carpels. If all four whorls (the calyx, corolla, androecium, and gynoecium) are present, the flower is described as complete. If any of the four parts is missing, the flower is described as incomplete. Flowers that contain both an androecium and a gynoecium are referred to as perfect, androgynous or hermaphrodites. There are two types of incomplete flowers: staminate flowers contain only an androecium, and carpellate flowers have only a gynoecium...

About Flower Flowers are introduced as the reproductive part of a plant. They are not only involved in reproduction but are also a source of food for other living organisms. They are a rich source of nectar. Flowers can either be • Complete • Incomplete. A complete flower is one that consists of sepals, petals, stamens and pistils. On the contrary, an incomplete flower is one that lacks one or more of these structures. A complete flower consists of two different parts: • Vegetative Part • Reproductive Part Also read: Let us have a detailed look at the different parts of a flower. Flower – L abelled Diagram Below is a well labelled and simple diagram of a flower for your better understanding. Parts of a Flower The calyx, corolla, androecium, and gynoecium are four whorls of modified leaves that constitute the flower. The sepals, petals, stamens, and pistils, respectively, constitute one of the flower parts in each of these whorls. The different parts of a flower are mentioned below: Vegetative Parts of a Flower The vegetative part of a flower consists of the following: • Petals: This is a bright-coloured part that attracts bees, insects, and birds. The colour of petals varies from plant to plant; some are bright while some are pale coloured. Thus, petals help us to differentiate one flower from another. • Sepals: Sepal is the green-coloured part beneath the petals to protect rising buds . Some flowers have fused petals-sepals while a few have separated petals-sepals.

Flowers are the reproductive parts of a plant. The parts of flower consist of four different kinds of whorls on the thalamus such as calyx, corolla, androecium and gynoecium. Calyx and corolla are accessory organs whereas, androecium and gynoecium are reproductive organs. Flowers are not only used for reproduction but also are a source of food for insects and birds which they feed on them for the nectar. Flowers can produce diaspores without fertilisation. And, pollination is one of the processes which is carried out by flower in which pollens are transferred from anthers to the stigma. Students can check NCERT Solutions for Class 6 Science Chapter 7 for better understanding. We have provided detailed information on parts of flowers in this article. Read on to find out about the descriptions of the parts of a flower and their functions. Parts of Flower: Description The flower is the reproductive part of the plant. They are found in flowering plants. The main function of flowers is to reproduce by the process of pollination. There are two types of pollination i.e., self-pollination and cross-pollination. Self-pollination occurs when pollen from the anther is deposited in the stigma of the same flower. Whereas, cross-pollination occurs when there is the transfer of pollen from the anther of one flower to the stigma of another flower. Few flowers can produce diaspores without fertilisation. The parts of a flower can be classified into two types; vegetative and reproductive. A...

Parts Of A Flower The main parts of a flower are the sepals, petals, stamens and carpels. Flowers that have all four of these parts are known as complete flowers. The stamens are the male parts; the carpels are the female parts. Most flowers have both male and female parts. On this page you’ll learn how to identify the basic flower parts and also find out what they do… Parts Of A Flower Diagram The diagram below shows the parts of a typical flower. Use the Notes: • Some flowers lack one or more of the four main parts (petals, sepals, stamens and carpels). Flowers such as these are known as incomplete flowers. • The carpels of many flowers are fused (joined together) into a single structure known as a pistil, as shown in the diagram above. • Most flowers have both male parts and female parts, but the flowers of some species produce flowers that are either male (i.e. lacking female parts) or female (i.e. lacking male parts).
