Answer 1

Plant hormones (also known as phytohormones) are organic substances that regulate plant growth and development. Plants produce a wide variety of hormones, including auxins, gibberellins (GA), abscisic acid (ABA), cytokinins (CK), salicylic acid (SA), ethylene (ET), jasmonates (JA), brassinosteroids (BR), and peptides

Answer 2

Answer:

Explanation:

Phytohormones.

*Plant hormones are chemical compounds present in very low concentration in plants. They are derivatives of indole (auxins), terpenes (Gibberellins), adenine (Cytokinins), carotenoids (Abscisic acid) and gases (Ethylene).

*These hormones are produced in all parts of the plant and are transmitted to various parts of the plant.

*They may act synergistically or individually. Roles of different hormonescan be complementary or antagonistic.

*Hormones play an important role in the processes like vernalisation, phototropism, seed germination, dormancy etc. along with extrinsic factors.

*Synthetic plant hormones are exogenously applied for controlled crop production.
