Its chemical formula is C19H22O6 (GA3).It is also an organic alkali: 6-furfuryl amino purine similar to adenine. Its chemical formula … Read more

Gibberellin and Cytokinin

GibberellinThe gibberellin is the plant hormone that contains diterpenoids organic acid and acts as growth regulator of the plants. The fungus Gibberella fujikuroi is responsible for fooling seedling disease or bakanae disease. Eiichi Kurosawa ( a Japanese scientist) first identified this disease in 1926. Later on, Tokyo University showed that this fungus Gibberella fujikuroi produces … Read more

Auxin and Its Functions

Auxin is a indole radicle plant hormone which is produced by growing tip of a coleoptile and influence growth rate of the cells and also encourages the length of roots and stems of plants.This type of hormone contains different types of organic acid. The plant hormone auxin and its role were first discovered by Frits … Read more

Photosynthesis: Definition, Process and Its Significance

image of Photosynthesis

All the living organism needs energy to perform their different normal metabolic functions. Food is the source of the power of the living body. Chlorophyll-containing plants produce foods by using solar energy. This particular function for creating their food is known as photosynthesis. French physiologist Henri Dutrochet (1837) first showed that the green parts of … Read more

Fermentation Vs Respiration : Definition, Types and Differences

The term ‘ferment’ is derived from the Latin word ‘fervere’ meaning “to boil.” In the late 14th century, alchemists described fermentation process and it became the subject of scientific investigation in the 16th century. In the 1860s, Louis Pasteur studied the fermentation process. In 1897, German chemist Eduard Buechner first used fermentation process scientifically and … Read more

Photosynthesis vs Chemosynthesis: Definition, Differences and Examples

image of Photosynthesis

All living organism needs energy to perform their different normal metabolic functions. Food is the source of energy of the living body. Photosynthesis is the process by which the chlorophyll-containing green plant and algae synthesizes glucose (carbohydrates) and evolves oxygen using CO2 of the air and water in the presence of sunlight. During the photosynthesis, … Read more
