text: Despite their diversity, angiosperms are clearly united by a suite of synapomorphies (i.e., shared, derived features) including 1) ovules that are enclosed within a carpel, that is, a structure that is made up of an ovary, which encloses the ovules, and the stigma, a structure where pollen germination takes place, 2) double fertilization, which leads to the formation of an endosperm (a nutritive tissue within the seed that feeds the developing plant embryo), 3) stamens with two pairs of pollen sacs, 4) features of gametophyte structure and development, and 5) phloem tissue composed of sieve tubes and companion cells (see Doyle and Donoghue, 1986; Judd et al. 2002; P. Soltis et al., 2004; and D. Soltis et al., 2005, for further discussion).
