What is the function of cytokinins?
Cytokinins are plant hormones that regulate cell division and differentiation, promote shoot growth, delay leaf senescence, and help plants respond to stress. They play a crucial role in plant growth and development by promoting cell division and maintaining meristem activity.
What are the characterstics of cytokinin?
Cytokinins are plant hormones that promote cell division and growth. They also influence apical dominance, root growth, and leaf senescence. Additionally, cytokinins play a role in regulating plant responses to environmental stresses.
Where are cytokinins produced in a plant?
Cytokinins are primarily produced in the root tips and developing seeds of plants. They are also synthesized in other tissues, such as shoot apical meristem and young leaves.
Is cytokinins involved in photosynthesis?
Cytokinins are not directly involved in photosynthesis. They are plant hormones that regulate various growth and developmental processes in plants, such as cell division, leaf senescence, and root development. Photosynthesis is a biochemical process that uses light energy to convert carbon dioxide and water into glucose and oxygen.
What effect does too much cytokinins have on plants?
Too much cytokinins in plants can lead to excessive cell division and proliferation, resulting in abnormal growth such as increased shoot branching and small leaves. This can also disrupt the balance between cytokinins and other hormones, leading to overall growth abnormalities and reduced plant health.
Effects of cytokinins on the delay of senescence in detached leaves?
Cytokinins are plant hormones that play a crucial role in delaying senescence, or aging, in detached leaves. They help to maintain chlorophyll levels, enhance protein synthesis, and promote cell division, which collectively contributes to prolonged leaf vitality. By inhibiting the degradation of chloroplasts and delaying the onset of metabolic changes associated with aging, cytokinins can significantly extend the functional lifespan of leaves after detachment. Overall, their application can effectively mitigate the typical signs of senescence in plant tissues.
What part of plant hormones prevents senescence?
cytokinins

What is the function of cytokinins found in developing seeds and fruits?
Cytokinins are plant hormones that play a crucial role in the growth and development of seeds and fruits. They promote cell division and growth, influencing processes such as seed germination, fruit development, and ripening. Additionally, cytokinins help regulate nutrient mobilization and delay senescence, ensuring that developing seeds and fruits receive the necessary resources for optimal growth. Their overall function is to enhance plant productivity and reproductive success.
What do cytokinins cause?
Cytokinins are a class of plant hormones that promote cell division, shoot formation, and growth in plants. They play a crucial role in regulating various physiological processes, including leaf expansion, axillary bud growth, and delaying senescence (aging) in leaves. Additionally, cytokinins help balance the effects of auxins, another group of hormones, to ensure proper plant development and response to environmental stimuli.
What are the characterstics of cytokinin?
Cytokinins are plant hormones that promote cell division and growth. They also influence apical dominance, root growth, and leaf senescence. Additionally, cytokinins play a role in regulating plant responses to environmental stresses.

What is cytokinins used for?
Cytokinins are plant hormones that promote cell division and regulate growth and development in plants. They are commonly used in agriculture to stimulate plant growth, improve crop yield, and delay aging processes in harvested plants. Additionally, cytokinins are used in tissue culture techniques to promote the growth of plant tissue in vitro.
What effect does too much cytokinins have on plants?
Too much cytokinins in plants can lead to excessive cell division and proliferation, resulting in abnormal growth such as increased shoot branching and small leaves. This can also disrupt the balance between cytokinins and other hormones, leading to overall growth abnormalities and reduced plant health.
