Plant Growth and Development

The two aspects of growth in living organisms are quantitative and qualitative. Quantitative growth refers to an increase in the length, breadth, size, volume, body mass, dry weight, and number of cells, while qualitative growth refers to a change in the nature of growth involving development, differentiation, and a more complex state.

Growth is defined as a permanent, irreversible increase in the bulk of an organism, accompanied by a change of form.

The three types of meristems in multicellular (vascular) plants are apical, intercalary, and lateral.
