Vedclass · Answer

(B) The growth of leaves in higher plants is primarily determined by the activity of meristematic tissues located at the margins of the leaf primordia.This type of growth is known as marginal growth,which allows the leaf blade (lamina) to expand.Additionally,in some plants,intercalary meristems may contribute to the elongation of the leaf base or petiole.Therefore,the growth of leaves is characterized by marginal and intercalary growth patterns.
