Question:
Coconut milk factor is:
Coconut milk factor is:
Updated On: Jun 23, 2024
- An auxin
- A gibberellin
- Abscisic acid
- Cytokinin
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Coconut milk factor is commonly associated with being a source of cytokinins, which are a type of plant hormone. Cytokinins are involved in various plant growth and development processes, including cell division and differentiation.
So, the correct option is (D): Cytokinin

- Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repair mechanisms. In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025

Plant Growth Regulators
What is a plant growth regulator?
Plant growth regulators (PGRs) are chemicals used to modify plant growth such as increasing branching, suppressing shoot growth, increasing return bloom, removing excess fruit, or altering fruit maturity.
Types of Plant Growth:
There are the following types of plant growth.
- Primary and Secondary Growth: The growth of a plant is termed primary when the same happens through the mitotic division of the meristematic cells which are present at the root and the shoot of the plants.
Whereas, the secondary growth in a plant takes place through the division of the secondary meristem, which, in turn increases the diameter of the body of the plants.
- Primary and Secondary Plant Growth
- Unlimited Growth
- Limited Growth
- Vegetative Growth
- Reproductive Growth
The five groups of plant growth regulators used in fruit crops include:
- Auxins: Auxins are one of the most important plant hormones. The chief naturally occurring auxin is indole-3 acetic acid – IAA and other related compounds.
- Gibberellins: Gibberellins are an extensive chemical family based on the ent-gibberellane structure. The first gibberellin to be discovered was gibberellic acid. Now there are more than 100 types of gibberellins.
- Cytokinins: These are produced in the regions where cell division occurs; mostly in the roots and shoots. They help in the production of new leaves, lateral shoot growth, chloroplasts in leaves etc.
- Absicisic Acid: Absicsic acid controls the dormancy of buds and seeds, inhibits shoot growth and is involved in regulating water loss from plants.
- Ethylene: Ethylene is a simple, gaseous plant growth regulator, synthesised by most of the plant organs includes ripening fruits and ageing tissues.
