Question

Match the following columns:

Column 1	Column 2
Auxin	Apical dominance
Cytokinin	Shoot development
Gibberellin	Dormin
Abscisic acid	Parthenocarpy

Answer 1

A. Auxin 1. Apical dominance

1. When apical bud grows taller in comparison to the other lateral branches because of auxin hormone the condition is known as Apical dominance.
2. Apical bud causes the lateral buds to remain dormant because of high concentration of auxin.

B. Cytokinin 4. Parthenocarpy

1. Plant fruit set is highly dependent on phytohormone biosynthesis and crosstalk.
2. The role of Cytokinin's in fruit development is still incompletely understood.

C. Gibberellin 2. Shoot development

1. The main plant hormone that promotes shoot growth is gibberellin.
2. Its basic function is to promote cell division and elongation.
3. It also plays a significant part in seed germination and flowering.

D. Abscisic acid 3. Dormin

1. Abscisic acid (Dormin, Abscisin II) is a plant hormone that controls ion homeostasis and metabolism and prevents germination and seedling growth.
2. Abscisic acid is regarded as dormant since it creates dormancy in buds, underwater stems, and seeds.

Column I	Column II
A. Auxin	1. Apical dominance
B. Cytokinin	4. Parthenocarpy
C. Gibberellin	2. Shoot development
D. Abscisic acid	3. Dormin
