Introduction to Growth and Development in Plants -
- Development is the sum of two processes: growth and differentiation.
- To begin with, the development of a mature plant from a zygote (fertilised egg) follow a precise and highly ordered succession of events.
- During this process, a complex body organisation is formed that produces roots, leaves, branches, flowers, fruits, and seeds, and eventually, they die
- The first step in the process of plant growth is seed germination.
- The seed germinates when favourable conditions for growth exist in the environment.
- In the absence of such favourable conditions, the seeds do not germinate and go into a period of suspended growth or rest.
- Once favourable conditions return, the seeds resume metabolic activities and growth takes place.
