Abstract
A plant embryo can be defined as a new individual arising from a single cell and having no vascular connection with maternal tissue (12). Embryos formed during sexual reproduction and attached to adjacent tissue by suspensors, obviously develop from single cells (zygotes) and, thus, fit this definition. However, somatic (nonzygotic or adventive) embryos produced in plant tissue cultures often appear as buds, broadly attached to underlying tissue, and this has caused some confusion as to whether or not they originated from single cells.
