'Both growth and differentiation in higher plants are open'. Comment.

(N/A) Growth and differentiation in higher plants are referred to as 'open' because these plants possess meristematic tissues that retain the capacity to divide throughout their life cycle.
These meristems are located at specific positions,such as the root and shoot apices,and continuously produce new cells that differentiate into various specialized tissues.
Unlike animals,where growth is determinate and stops after a certain stage,plants can continuously add new organs and tissues,allowing for indeterminate growth.
