Summary Introduction
Introduction:
Plant embryogenesis is a mechanism through which the plant generates an embryo through asymmetric type of cell division from a fertilized ovule. Embryogenesis occurs through the differentiation of the undifferentiated set of cells into organs and tissues. The formation of the leaf is not included in the embryogenesis.
