Cytokinins. The cytokinin hormones stimulate tissue growth and cell division, and the amount of activity that these hormones exert is directly proportional to the amount of auxins that are present.
Is ethylene important for cell division?
Within a few hours, ethylene will block cell division using a dose-response curve that is quite similar to the curve used for the majority of the gas’s other activities. Experiments with seedlings grown under hypobaric settings reveal that the gas naturally controls plumular growth and cell division in the apical portion of the plant. [Citation needed]
Which plant hormone promotes cell division * 2 points?
Therefore, the response that is right is cytokinin.
What is the function of gibberellins?
What is the primary role that gibberellins play in the plant? Gibberellins are a kind of plant growth regulator that, by encouraging the elongation of plant cells, let plants attain a greater height. They also play important roles in the process of germination, the lengthening of the stem, the ripening of the fruit, and the flowering of the plant.
Which plant growth hormones is highly required for growth of cell?
Cytokinins are a kind of plant growth agent that primarily stimulates cell division and has little to no influence, if any, on extension growth. Cytokinins’ primary contribution to biology is their ability to stimulate the division of cells.
What is essential for cell division?
The creation of genetic variation relies on the process of cell division. Cell division is an essential step in the transformation of a unicellular creature into a new organism. This transformation can only take place in unicellular organisms. Significance of Cell division.

Which plant hormone is helpful in making RNA and protein A gibberellins B auxin C cytokinins D ethylene?
Cytokinins plant harmone, also known as cytokinins, play an important role in the production of RNA and protein.
Do gibberellins help in cell division?
Our findings lend credence to the concept that gibberellin acts on the intercalary meristem to initiate cell elongation before going on to drive cell division as a consequence of cell growth. This hypothesis is supported by our findings.
Which of the following plant hormones promotes cell division and prevents senescence?
The solution that you are looking for is cytokinin. Cytokinins are a group of plant growth agents that stimulate cell division and organ creation, postpone senescence, promote the development of lateral buds, improve chloroplast development, and enhance cell expansion in cotyledon leaves.
Which hormone is helpful in promoting cell division and opening of stomata?
Cytokinins, when present in low amounts that are physiologically relevant, cause stomata to open.
What is the function of cytokinin?
Cytokinins are a class of plant growth regulators that are principally responsible for the process of cell division in the plant’s roots and shoots. This hormone contributes to the promotion of cell proliferation, development, and differentiation. It also has an effect on apical dominance and delays the senescence of leaf tissue.
What is cytokinin in plants?
- Cytokinins are N6-substituted adenine derivatives that influence many aspects of plant growth and development.
- Some of these aspects include cell division, shoot initiation and growth, leaf senescence, apical dominance, sink/source relationships, nutrient uptake, phyllotaxis, and vascular, gametophyte, and embryonic development, as well as phyllotaxis.
- Cytokinins are produced in the cytoplasm of
Is auxin a plant hormone?
Auxin refers to any member of a group of hormones produced by plants that are responsible for regulating growth, in particular through encouraging the extension of cells in stems.
What are auxins in plants?
Auxin is an important hormone that plays a role in the regulation of plant growth and development. It directs the processes of cell division, elongation and differentiation, embryonic development, root and stem tropisms, apical dominance, and the transition to flowering.
What are auxins and cytokinins?
- Auxin and cytokinin are two important hormones that play a role in regulating the growth and development of plants.
- The levels of hormones in cells and tissues are carefully regulated throughout development, on a 24-hour basis, and in reaction to environmental factors.
- This is because hormones are active at very low concentrations and they are responsible for the regulation of dynamic processes.
Which of the following promotes cell division?
Cytokinins are the right answer in this case. Cytokinins, often known as CK, are a group of plant growth chemicals that encourage cytokinesis, also known as cell division.
