NEET BIOLOGY

Detailed explanation-1: -Cytokinin is the hormone responsible for this. Cytokinin is known as the hormone responsible for cell division. It stimulates the metabolism and the formation of flowers on side shoots, and as such it is a counterpart to auxin.

Detailed explanation-2: -The phytohormone auxin is a major regulator of plant growth and development. Many aspects of these processes depend on the multiple controls exerted by auxin on cell division and cell expansion.

Detailed explanation-3: -Auxins are a powerful growth hormone produced naturally by plants. They are found in shoot and root tips and promote cell division, stem and root growth. They can also drastically affect plant orientation by promoting cell division to one side of the plant in response to sunlight and gravity.

Detailed explanation-4: -Auxin and cytokinin are critical growth hormones in plant development and are naturally present within the plant at variable concentrations throughout the season.

Detailed explanation-5: -Answer: Auxin is a plant growth hormone that can be created chemically or produced biologically by the plant. In biological synthesis, the natural hormone is represented by the symbol IAA, standing for indoleacetic acid.
