The gaseous plant growth regulator is used in plants to

Ethylene is a gaseous plant hormone. It induces development of adventitious roots on various types of cutting. It promotes the development of lateral roots and growth of root hairs. Cytokinin helps to overcome the apical dominance. Auxin is used to kill dicot weeds. Gibberellin speeds up the malting process

The gaseous plant growth regulator is used in plants to: 1. kill dicotyledonous weeds in the fields 2. speed up the malting process 3. promote root growth and root hair formation to increase the absorption surface 4. help overcome apical dominance Past Year (2019 onward - NTA Papers) MCQs Plant Growth and Development Botany NEET Practice Questions, MCQs, Past Year Questions (PYQs), NCERT Questions, Question Bank, Class 11 and Class 12 Questions, and PDF solved with answers

Concept: • Plant growth regulators (PGRs) are defined as small, simple molecules of diverse chemical composition. • They are also described as plant hormones or phytohormones. • PGRs are classifiedinto two broad groups based on their functions in a living plant body. • One group of PGRs is involved in growth-promoting activities, such as cell division, cell enlargement, pattern formation, tropic growth, flowering, fruiting, and seed formation • The PGRs of the other group play an important role in plant responses to wounds and stresses of biotic and abiotic origin. • A few examples of PGRs are indole-3-acetic acid, abscisic acid, terpenes (gibberellic acid, GA3 ), or gases (ethylene, C 2H 4 ). Explanation: Option 1: • Auxin is used to kill dicotyledonous weeds in the fields. • ‘Auxin’ is applied to the indole-3-acetic acid (IAA), and to other natural and synthetic compounds having certain growth regulating properties. • It alsohelps to initiate rooting in stem cuttings. Option 2: • Gibberellin speeds up the malting process. • Gibberellins is a promoter among PGR. • Gibberellins, cause fruits like apples to elongate and improve their shape andalso delay senescence.Thus, the fruits can be left on the tree longer so as to extend the market period. • GA 3 is used to speed up the malting process in the brewing industry. Option 3: • Ethylene is a gaseous plant hormone. • It induces the development of adventitious roots on various types of cutting. • It promotes the development o...
