FAQs on 6 Days Study Plan Plant - Growth & Development - Biology Class 11 - NEET

1. What are the phases of growth in plants?
Ans. The phases of growth in plants are as follows: - Meristematic phase: This phase involves the division of cells in the meristems, which are regions of active cell division. - Elongation phase: In this phase, the cells grow in size and elongate, leading to an increase in the length of the plant. - Maturation phase: During this phase, the cells differentiate into specific types and acquire specialized functions.
2. What are auxins and how do they affect plant growth?
Ans. Auxins are a type of plant hormone that plays a crucial role in regulating plant growth and development. They are primarily responsible for promoting cell elongation, controlling apical dominance, and facilitating root initiation and growth. Auxins also regulate phototropism, gravitropism, and the formation of adventitious roots.
3. What is the role of abscisic acid (ABA) in plants?
Ans. Abscisic acid (ABA) is a plant hormone that primarily functions in stress responses, particularly in drought conditions. It helps in the closure of stomata to reduce water loss through transpiration. ABA also plays a role in seed dormancy and regulates the synthesis of other hormones, such as ethylene.
4. How do gibberellins influence plant growth?
Ans. Gibberellins are plant hormones that promote stem elongation, seed germination, and flowering in plants. They stimulate cell division and elongation, resulting in increased plant height. Gibberellins also influence the development of leaves, fruits, and flowers.
5. What are cytokinins and how do they regulate plant growth?
Ans. Cytokinins are plant hormones that promote cell division and delay senescence (aging) in plant tissues. They are involved in various physiological processes, such as shoot initiation, shoot and root growth, and the control of apical dominance. Cytokinins also interact with other hormones, such as auxins, to regulate plant growth and development.
