However, other alternatives exist, including one where the two perianth whorls of Monocotyledoneae are homologous with the calyx (outer perianth whorl) of Pentapetalae by loss of the ancestral two innermost perianth whorls. The megasporangium, together with its integument, makes up the ovule. This 3N cell will divide repeatedly to form the endosperm, the stored nutritive material inside the seed. This process, known as synorganization, is thought to have increased pollination efficiency and helped trigger some of the most spectacular radiations in angiosperms, such as the Asteraceae and Orchidaceae 35. To address this problem, there are three complementary approaches 7. Because of the innumerable varieties of the fruit and/or flower-bearing plants, they have variegated colors and shapes of leaves, flowers and fruits.
