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.
What part of plant hormones prevents senescence?
cytokinins

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.

This can also disrupt the balance between cytokinins and other hormones, leading to overall growth abnormalities and reduced plant health.
Why do plant leaves turn brown and yellow?
Plant leaves turn brown and yellow due to a process called senescence, which is a natural aging process in plants. During senescence, chlorophyll (the green pigment in leaves) breaks down, causing the leaves to lose their green color and turn yellow. Additionally, factors such as nutrient deficiencies, diseases, pests, and environmental stress can also contribute to the browning and yellowing of plant leaves.
Why do leaves turn brown in autumn?
Due to leaf senescence. In autumn the leaves stop being the sink for phloem transport so the nutrient supply dwindles so the leaves age and turn brown (since there are no nutrients to carry on producing more chlorophyll etc.). Senescence occurs due to reduced levels of cytokinin (plant "hormone") production.
What is a sentence using the word senescence?
A human's senescence often accompanies senility.
