Where are cytokinins found?
Cytokinins are present in all plant tissues. They are abundant in the root tip, shoot apex, and immature seeds. Their endogenous concentration is in the low nanomolar range. Typically, several types of cytokinins and their modified forms are present in a given tissue.
Where are cytokinins found in a plant what is their function?
Cytokinins are synthesized in the roots and are usually derived from adenine. They move upward in the xylem (woody tissue) and pass into the leaves and fruits, where they are required for normal growth and cell differentiation.

What are cytokines in plants?
It has been recognized that cytokinins are plant hormones that influence not only numerous aspects of plant growth, development and physiology, including cell division, chloroplast differentiation and delay of senescence but the interaction with other organisms, including pathogens.Dec 19, 2019
What is the function of cytokinins in plants?
Cytokinins promote cell division and increase cell expansion during the proliferation and expansion stages of leaf cell development, respectively. During leaf senescence, cytokinins reduce sugar accumulation, increase chlorophyll synthesis, and prolong the leaf photosynthetic period.Jun 1, 2021
What is the main function performed by cytokinin?
Cytokinins are a group of plant growth regulators which are primarily involved in performing cell division in plant roots, shoot system. This hormone helps in promoting the cell's growth, development, differentiation, affecting apical dominance and delay in leaf senescence.
Where is cytokinin found in plants Class 10?
Cytokinin is produced in root apical meristems (tip of roots), move upward and travel up the stem via xylem.
What is plant cytokinin class 10?
Cytokinins are a group of plant growth regulators which are primarily involved in performing cell division in plant roots, shoot system. This hormone helps in promoting the cell's growth, development, differentiation, affecting apical dominance and delay in leaf senescence.
What is the role of cytokinin in plants?
Cytokinins promote cell division and increase cell expansion during the proliferation and expansion stages of leaf cell development, respectively. During leaf senescence, cytokinins reduce sugar accumulation, increase chlorophyll synthesis, and prolong the leaf photosynthetic period.Jun 1, 2021
Do plants have cytokinin?
Cytokinins are a class of plant-specific hormones that play a central role during the cell cycle and influence numerous developmental programs. Because of the lack of biosynthetic and signaling mutants, the regulatory roles of cytokinins are not well understood.
Is cytokinin present in human body?
Cytokinin is a plant growth hormone that is responsible for cell division (cytokinesis) and helps in the growth of young fruits. In humans: Cytokinins are important for the immune response of the body. They form an important component of the inflammatory response.
