The development of the seed plant sporophyte can be broken down into three major stages (Figure 17.2): embryogenesis, vegetative development, and reproductive development. (...) An essential feature of this basic architecture is the presence of apical meristems at the tips of the root and shoot axes (see Figure 17.2), which are key to sustaining indeterminate patterns of vegetative growth.
