In this article we will discuss about the composition of sporopollenin in spores and pollen. Sporopollenin is the major component of exine of spores and pollen. 'It is most extraordinarily resistant material known in the organic world'. It is extremely resistant to non-oxidative chemicals, enzymes and strong chemical reagents. It is chemically stable and remains unchanged in pollen grains that [...]
In this article we will discuss about:- 1. Distribution of Sporopollenin 2. Chemistry of Sporopollenin 3. Production and Deposition 4. Functions. Distribution of Sporopollenin: It was first observed and named as "sporonin" by John (1814) and latter characterized by Berzelius (1830). Fossil green algae dating back to Devonian period have been shown to contain sporopollenin. The oldest sporopolleninous acritarchs occur [...]
