NCERT Solutions for Class 11 Biology Chapter 15 - Plant Growth and Development

iacst-2022

In this chapter, understanding the process of plant growth and development has been imparted. Here, students will learn about the factors that govern and control the plants' organizational and developmental processes. These factors that have been mentioned are intrinsic, i.e. internal and extrinsic, i.e. external to the plants. Few more topics explained are Growth Differentiation, Redifferentiation and Dedifferentiation, Plant Growth Regulators, Development, Vernalization, Photoperiodism, and more. Explanations of the sub-topics of this chapter are given below.

  • Plant Growth
  • Differentiation, Redifferentiation, and Dedifferentiation
  • Plant Development
  • Regulators regulating Plant Growth
  • Photoperiodism
  • Vernalisation

Discussed under this chapter is a section of elements that look after and control the formative cycles. This is the last chapter under Unit IV - 'Plant Physiology' of class 11 Biology. Here, it is explained how plants' development is a combination of two different processes, i.e. growth and differentiation. Essentially, it has been elaborated that after evolving into a mature plant from a zygote comes a brief and highly organized succession of events. In the process of plant growth, the initial step that comes is the germination of seeds.
