Sporopollenin is found in the exine of pollen grains.
- Exine: The exine is the outermost layer of the pollen grain wall.
- Sporopollenin: Sporopollenin is a complex biopolymer that is highly resistant to decay and degradation.
- Composition: The exine is primarily composed of sporopollenin, a substance that provides protection to the pollen grain.
- Function: Sporopollenin helps prevent desiccation and provides mechanical strength to the pollen grain.
- Impervious: Sporopollenin is highly resistant to environmental factors such as heat, cold, chemical attack, and microbial activity.
- Pollen dispersal: The presence of sporopollenin in the exine allows pollen grains to be dispersed over long distances by wind, water, or other pollinating agents.
- Chemical nature: Sporopollenin is chemically stable and does not readily break down, making it an ideal material for preserving and fossilizing pollen grains.
- Applications: Sporopollenin has various applications in paleobotany, palynology, and drug delivery systems due to its durability and inertness.
Therefore, sporopollenin is found in the exine, the outer layer of the pollen grain wall.
