Flowers are the most beautiful structures on the surface of plants. They are the organs of sexual reproduction in plants. They form as a bud, grow into flower and then convert into fruit after pollination. These flowers have many uses to man, animals and the ecosystem around

Uses of flowers to man

Man has been fascinated with flowers for their fragrance, color, beauty, and feel. For the man, a flower is a symbol of love, holiness, and also a good omen. The flowers are used as

1. Source of food

All the vegetarian food materials we consume are products of flowers.

We consume those fruits and seeds as our regular diet.

Examples of fruits include grapes, mango, orange, apples, cucumber, tomato, etc.

Examples of seeds include wheat, rice, maize, grams, nuts, etc.

Examples of flowers that we eat include cauliflower.

2. Source of honey

Honey is formed by the honey bees from the nectar which is collected from the flowers.

It is a sweet liquid deposited into the honeycombs. These honeycombs are filled with honey by the worker honey bees.

Honey bees visit the flowers, suck up the nectar and reach the comb. The nectar undergoes changes in the bee and is released as honey.Honey bee collecting honey

This honey is used for various purposes like in medicine preparation, food, sweetening agents.

Due to its contents like phenols and antioxidants, it is used for health purposes.

3. Source of medicine

Flowers are also a good source of plant medicine. An anticancer drug-like vincristine an alkaloid is produced from flowers and other parts of the plant.

Besides, medicine like atropine, Hyoscyamus, essential oils like eugenol, menthol is obtained from flowers.

These flower parts like the petals and sepals are used to extract the fragrance in the form of essential oils.

These essential oils are a mixture of volatile oils. They can be extracted by the solvent extraction method or by steam distillation, Supercritical fluid extraction, ultrasound methods, etc.

7. Insect repellents

Insect repellents have one of the biggest markets. We need insect repellents to keep mosquitoes, cockroaches, houseflies away.

Synthetic insecticides like organophosphorus poisons have a lethal effect on humans and other animals.

To minimize this natural insect repellant like pyrethrin is used. This pyrethrin is obtained from the plants of Chrysanthemum Cinerariaefolium.

It has a toxic effect on the respiratory system of insects. Thus, when used at homes or workplaces, we humans are spared of insects bite.

Uses of flowers to plants.

For Sexual reproduction by pollination

The main use of flowers is to help in sexual reproduction by the transfer of male gametes. Flowers give of pollen grains.

This pollen is carried off by the wind, animals, or even water. Once, they reach another flower, the pollen enters the female organ and forms a zygote.

This zygote forms an embryo and then converts into a fruit. These fruits contain seeds that can grow into a new plant when it reaches the soil.

So, a flower acts in sexual reproduction and thereby helps in plant propagation.

Even in agriculture, flowers help in higher yield due to pollination. Hence, male and female plants are given special importance during cultivation.

Uses to Animals and Environment

The uses of flowers also extend to nature. The flowers regulate breeding and support the food cycle.

9. For breeding of Insects and Birds

Flowers provide food in the form of nectar. So, the growth of flowers is good for insects, larva, and also birds. Birds lay eggs and hatch them to give birth to young ones. These young ones need food to grow.

The mother bird tries to fetch some insects roaming around. These insects keep roaming around in search of food. This food is most delicious in the form of nectar from flowers.

So, we can notice, that birds lay eggs when there is a chance for an abundance of insects and larvae. This in turn is dependent on the growth of flowers on the plant. On the whole, the plants support breeding by producing flowers.

10. Beauty to nature

The presence of flowers adds natural beauty to the environment around them. The growth of flowers in plenty keeps the environment lively.

These flowers attract all sorts of animals like birds, cattle, and even men. Hence, the flowering season is celebrated in most parts of the world.
