My story is entitled The essence of flowers.

Flower is known as a bloom or blossom. The reproductive structure found in flowering plant that is the plants of the division Magoliophyta also called Angiosperms.

The biological function of a flower is to facilitate reproduction usually by some means of a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing or the fusion of sperm and eggs from different individuals in a population or allow selfing the fusion of sperm and egg from the same flower when self pollination occurs.

Pollination seems to be of two types which happens to be Self pollination and Cross pollination.

Self pollination happens when the pollen from the anther of the flower is deposited on the stigma of the same flower or another flower in 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. Self pollination happened in flowers where the stamen and the carpel matures at the same time and are positioned for the pollen to land on the flower’s stigma.

Again, some flowers produce diaspores without fertilization. Flowers contain sporangia and are the site where gametophytes develop.

Other flowers have evolved to be active to some Animals, so as to cause them to be vectors for the transfer of pollen. Also fertilization, the ovary of the flower develops into fruits containing seeds.

Again, in addition, to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to bring beauty to their environment and also as object of romance, ritual, religion, medicine and as a source of food.

The flower has floral parts. The essential parts of a flower can be considered into two parts the vegetative part consisting of petals and associated structures in the perianth and the reproductive or sexual parts. A stereotypical flower consists of four kinds of structures.

Each of these kinds of parts is arranged in a whorl on the receptacle. The four main parts of the flower includes Perianth: which is collectively the calyx and the corolla from the perianth.

Calyx: the outermost whorl consisting of units called sepals, these are typically green and enclose the rest of the flower in a bud stage. They can be absent or prominent and petal-like in some species.

Corolla: the next whorl toward the apex composed of units called petals which are typically thin, soft and coloured to attract animals that helps the process of pollination.

The next whorl of the flower which is the plant reproductive morphology, Androecium and Gynaecium.

 Androecium is the next whorl consisting of units called stamens. Stamens consists of two parts a stalk called a filament, topped by an Anther where pollen is produced by meiosis and eventually dispersed entirely.

Also, Gynoecium is known as inner most whorl of a flower consisting of some sort of units called carpels.

The carpel or multiple fused carpels form a hollow structure called an ovary, which produces ovules internally. Ovules are megasporangia and they in turn produce megaspores by Meiosis which develops into female gametophytes.

The gynoecium of a flower is also described using an alternative terminology wherein the structure one sees in the innermost whorl is called the pistil.

A pistil may seem to consist of a single carpel or a number of carpels fused together.

The sticky tip of the pistil, the stigma is the receptor of pollen. The relationship to the gynoecium on the receptacle is described as hypogynous beneath a superior ovary or epigynous above inferior ovary.

There is a variation in the flower structure. The four main parts of the flower are defined by their positions on the receptacle. In some family like Ranunculaceae, the petals are greatly reduced. The sepals are colourful and petal like.

Some flowers have modified stamens that are petal like, the double flowers of Peonies and Roses are mostly petal and stamens.

Also many flower parts are fused together, fused parts originating from the same whorl are connate while fused parts originating from different whorls are connate. The parts that are not fused are free. Petals fused into a tube or ring and falls away as a single unit, they are sympetalous also called gamopetalons.

Cornate petals may have a distinctive region the cylindrical base is the tube. 

The expanding region is the throat and flaring out region is the limb.

A sympetalous flower with bilateral symmetry with an upper and lower lip is bilaterate. Flowers with connate petals or sepals may have a shaped corolla or Calyx.

There are the primordia of floral appendages such as sepals, petals, stamens, and carpels.

Flowers have symmetry. The Flower is said to be actinomorphic or regular.

When flowers are bisected and produce only one line that produces symmetrical halves, the flower is said to be irregular or zygomorphic. Also flowers may be directly attached to the plant at their base. The stem or stalk subtending a flower is called a peduncle. Where a peduncle supports more than one flower the stem connecting each flower to the main axis is called pedicels.

The apex of a flowering stem forms a terminal swelling which is called the torus or receptacle.

The collective cluster of flowers is termed as inflorescence.

A single daisy or sunflower is an inflorescence composed of numerous flowers or florets. An inflorescence may include specialized items and modified leaves known as bracts.

The floral formula is also a way in representing the structure of the flower using specific letters, numbers, symbols, presenting substantial information about the flower in a compact form. The format of floral formulae differs in different parts of the world.

The structure of the flower can also be expressed by the means of floral diagrams. The floral structure and evolution. A flower also develops on a modified shoot or axis from a determinate apical meristem determinate meaning the axis grows to a size. The classical plant morphology are then interpreted as highly modified leaves.

The transformation to flowering is one of the major phase changes that a plant makes during its life cycle. The entire transition must take place at a time that is favourable for fertilization and the formation of seeds.

In addition the principal purpose of a flower is the reproduction of the individual species. All flowering plant are heterosporous, every individual plant produces two types of spores. Microspores are produced by meiosis inside anthers and megaspores are produced inside ovules.

Flowers do have both functional carpels and stamens.

The morphology of the flowers and the behaviour of plants. Cleistogamous flowers are self-pollinated, after which they may or may not open.

Some flowers have patterns called nectar guides. Anemophilous flowers are wind to move pollen of some sort from a flower to the next. Some examples include grasses, birch trees, and maples. 

Again the primary purpose or essence of the flower is reproduction. The flowers are the reproductive organs of plants.

Pollination is the movement of pollen from the anthers to the stigma. The joining of sperm to the ovules is also called fertilization.

Many plants also self-pollinate, pollen is moved from one plant to another. The study of pollination by insects is called Anthecology. Many Flowering plants also reflects light. 

The Roman goddess of flowers, gardens and the season of spring is Flora. The Greek goddess of spring, flowers and nature is Chloris. Flower giving is the way and means by which couples show affection in love. Flowers are also used as a sacrificial and burial objects.

Finally, most people use flowers to mark important events in their lives such as new births, tokens of love or esteem, wedding flowers, brightening decoration within an entire home, welcome home parties, for funeral flowers and the expression of sympathy for the grieving.
