What is the name of naturally occurring Auxin in plant?
A
1-napthaleneacetic acid (NAA)
B
2, 4-Dichlorophenoxyacetic acid (2, 4-D)
C
Indole 3-acetic acid (IAA)
D
1-napthoxyacetic acid (NOA)
Explanation: 

Detailed explanation-1: -This term is derived from the Greek word “auxein, ” which means “to increase” or “to grow.” Indole-3-acetic acid (IAA) is the most common plant hormone of the auxin class and it regulates various aspects of plant growth and development. Thus, the terms “auxin” and “IAA” are occasionally used interchangeably.

Detailed explanation-2: -Polar transport of the natural auxin indole-3-acetic acid (IAA) is important in a number of plant developmental processes. However, few studies have investigated the polar transport of other endogenous auxins, such as indole-3-butyric acid (IBA), in Arabidopsis.

Detailed explanation-3: -The most prevalent naturally occurring auxin in plants is Indole-3-Acetic Acid (IAA). Indole-3-Acetic Acid (IAA) is mostly synthesized in the apical buds of young shoots. It has been shown to stimulate cell elongation and division.

Detailed explanation-4: -Indole-3-acetic acid (IAA, 3-IAA) is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists.

Detailed explanation-5: -Auxins consists of both natural and synthetic auxins. Indole acetic acid is the most abundant natural auxin. Q.
