Kurinji flower blossom only once in 12 years. Why?

Flower name: kurinji Flower

Scientific name: Strobilanthes kunthiana
                   

                     Before flowering, a plant must attain the ripe-to-flower condition. To attain this condition, the plant must complete a period of vegetative growth. Attainment of this of this condition does not automatically lead to the initiation of flower primordial.
                     

                     Certain environment condition must follow. temperature and duration of light and dark periods within the 24 hours cycle are the two important environmental factors that influence the initiation of flower primordial in a plant that has attained ripe-to-flower condition.
                    

                      The response of a plant to this aspect of light is called photo periodism. When appropriate photo period is given to plant that has attained the ripe-to-flower condition, the metabolism is altered.
                    

                      This result in the formation of flower stimulus, which may be hormone. when this flower stimulus is translocated to the shoot apex, the vegetative shoot apex is transformed to reproductive shoot apex which results in the initiation of flower primordial.
                     

                      In natural conditions, the period taken to attain the ripe-to flower condition, and the period taken to obtain appropriate photo period differ widely among different plant species.
                        

                      Kurinji needs a period of 12 years for having to be subjected to cycle conductive to flowering.

TOP 10 CRIME🕵🏻‍♂️ THRILLER 😱 MOVIES TO WATCH IN 2021!

     A crime thriller film is a crime film sub-genre. The subgenre combines a normal genus of crime with a unique genre of thriller. Typically, the storyline is about and revolves around an assassin; a heist or a person hunting. Crime thrillers employ tension and suspension to develop action and psychological components.       Crime thrillers concentrate on the thrilling aspects of both successful and failed crimes. They centre on a criminal or a group of criminals rather than law enforcement, unlike police procedurals. These films, like the highly regarded Joseph and Nayattu, tend to emphasise on violent sequences, double-crossings, robberies, and killings as major themes. 10.The Gift (2005) When it comes to suspensory movies, the gift is really an underestimated and hidden gem. However, even then the applaudable material requires a watch and must be listed. The gift is a storey about a couple who one day get to know one of their old friends. When the a...

TOP 10 BEST ACTION JACKIE CHAN ✌️ MOVIES!

Jackie Chan is regarded as one of the finest actors of all time. After all, performance encompasses more than simply acting; a dancer, like a musician, a comedian, and, of course, a professional screen fighter, is a performer. While it's undeniable that Chan isn't a great actor, he's an unrivalled performer in the sense that he's not only a master martial artist with unrivalled speed, originality, and bravery, but he's also a comic presence that existed only during the silent period. It's no exaggeration to claim Chan is the successor of Buster Keaton, Gene Kelly, and Bruce Lee all at the same time. Like Keaton, he's the most brilliant creator of death-defying stunts as physical comedy; like Kelly, he's a brilliant choreographer who finds artistry in the way the human body moves through spaces and who also possesses a superhuman ability to execute those athletic moves; and like Lee, he's just a badass of a kung fu fighter who defined what a true mar...
