Chapter 30, Problem 1SQ
Summary Introduction
Concept introduction: Plants are the eukaryotic group of organisms that continue their growth and differentiation till their death. Meristematic cells present in their root and shoot tips are primarily responsible for this unlimited growth process. The case of animals is not similar, where they undergo division and produce new tissues only up to a stage in their life time.
