CONTEST OF THIS WEEK 2021#PHOTOGRAPHY #WONDERFUL FLOWERS

Good night all friends on Steemit.

On this occasion I will show you the flowers that I found in Aceh, beautiful flowers as below:

Flower

Flowers are modified leaves and stems around them. This modification is caused by the production of a number of enzymes stimulated by certain phytohormones. Flower formation is strictly genetically controlled and in many species is induced by certain environmental changes, such as low temperature, length of exposure, and availability of discuss (see section Flowers: Flower formation).

Flower

The formation and development of flowers The formation of flowers has long been a concern of people, because much of the economic value of cultivated plants depends on the formation of flowers. Flowers will not form before the tissue where it will appear has reached the stage of maturity (development) but is not too old (senile).

Flower

In tree-shaped plants, newly formed or still developing (adolescent) tissue will be very difficult to form flowers. Tissues that reach the maturity stage are often characterized by a high carbon-nitrogen ratio (C-N ratio). High carbon content because many metabolites have been buried in the form of polysaccharides in the tissue. Flower formation requires a lot of energy. A high C-N ratio is usually sufficient to encourage the formation of flowers.

Flower

However, there are many types of plants that require a trigger for flowers to appear. These triggers can be low temperature for some time (vernalization), length (duration) of exposure (photoperiod).

Flower

Botanically, a flower is the part of a plant that produces seeds. Pollination and fertilization take place in flowers. After fertilization, the flower will develop further to form a fruit.

Flower

In flowering plants, the fruit is the structure that carries and protects the seed.

Flower

The biological function of flowers is the sexual organ, as a container for the fusion of male gametes (microspores) and female (macrospores) to produce seeds.

That flowers are analogous to sexual organs in animals was scientifically realized only in the 17th century in Europe. Some flowers have bright colors that serve as attractants for pollination aids. Some other flowers produce heat or a distinctive smell, also aims to attract animals to help pollinate.

Flowers can also be considered as organs to survive in conditions that are less favorable for growth. Some plants will flower immediately if they experience a shortage or low temperature. The most famous example is the Bougai paper flower

that's what I can say to all my friends in the steemit world. I hope you enjoy seeing it

That's all i can say my friends
