Regeneration - Root and Shoot Morphogenesis
Higher plants have three kinds of regenerative activities;
All plants possess inherent ability to regenerate lost parts. For example when a part of mature tissues are removed from stem, the exposed mature cells undergo differentiation, division and re-differentiation to restore the normal pattern. When a branch is cut and wound is made-damaged tissues are cast off and new cells take this place. A wound also results in the formation of a zone of cells that form a thick protective layer. Induction of hormones like auxins and cytokinins that promote cell division is also a reaction to wound and part and parcel of regeneration. Mobilization of nutrients towards the site of injury, synthesis of new hormones, increased cell division and thickening of cell walls etc. are some of the responses and contribute to regeneration.
