Question

Which of the following is a coconut milk factor?
(a)Auxin
(b)ABA
(c)Morphactin
(d)Cytokinin

Answer 1

Hint: Coconut milk contains an active substance that helps in the cytoplasmic division. Coconut milk is the white flesh of the mature brown coconut that provides a number of health benefits. It is a good source of minerals and vitamins.

Complete answer:
Cytokinin is a coconut milk factor. They called it cytokinin because it induced cytokinesis or cytoplasmic division. Cytokinin in coconut milk was isolated by using tobacco callus growth-promoting assay as a guide during purification. Zeatin type of cytokinesis present in coconut milk.

Additional Information: -Cytokinin is a plant hormone that induces growth and development. It is one of the most studied hormones. Cytokinin triggers physiological responses through the regulation of gene expression.
-Cytokinesis is a part of the process of cell division, where the division of the cytoplasm occurs. It occurs after the process of Nuclear division. During cytokinesis, the spindle apparatus moves apart, and the chromatin material is divided among the separating daughter cells.
-The most abundant cytokinin in Arabidopsis is trans-zeatin that possesses isoprenoid side chains.
-Cytokinin also plays an important role in plant growth like shoot initiation and growth, leaf senescence, and photomorphogenic development.
Auxin: It is a plant hormone that is produced in the stem, bud, and root tips. Auxins inhibit the growth of lateral buds and promote stem elongation.
ABA: Abscisic acid is a plant hormone that has multiple roles in plant growth and development such as involved in the bud and seed dormancy, in the closure of stomata, and inhibits other hormonal actions.
Morphactin: It is the derivative of the fluorine compound and has very diverse effects on plant growth and development. In presence of other natural hormones, it shows both synergistic and antagonistic effects. It is very effective in lateral bud development.
So, the correct answer is ‘Cytokinin’.

Note: -Zeatin is a first identified naturally existing cytokinin, extracted from sweet corn for artificial production.
-The tobacco pith test for cell division is used to study the activity of cytokinesis.
-In some cases, when nuclear division occurs after cytokinesis, it leads to the formation of multinucleated cells.
- Unlike coconut milk, coconut water is actually a free endosperm.
