Another hypothesis is that orbicules participate actively in sporodenn formation by representing a transport system of sporopollenin between the tapetum and the developing microspores. This idea is based on observations of connections between orbicules and pollen sexines, mainly in grasses, or observations of a close contact between microspores and orbicules in other species.

Glossary

Theoretically, the pores or the imperfections on the chemically attacked surfaces were as a result of three reasons: Firstly, due to the remaining microspores resulting from unfinished densification; secondly, the existence of [beta]-TCP phase as the decomposition product which dissolved much faster than the pure HA phase; thirdly, the intrinsic chemical stability of the ceramics [19].
