Sporopollenin is found in -a)Exineb)Intinec)Cytoplasmd)NucleusCorrect ...
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.

Sporopollenin is found in -a)Exineb)Intinec)Cytoplasmd)NucleusCorrect ...
Explanation:
Sporopollenin is found in Exine:
- Sporopollenin is a major component of the exine layer of pollen grains.
- Exine is the outer layer of the pollen grain, which is made up of sporopollenin.
- Sporopollenin is a very resistant biopolymer that provides protection to the pollen grain from various environmental stresses.
- It is highly resistant to chemical and biological degradation, making the pollen grain durable and capable of surviving in various conditions.
- The presence of sporopollenin in the exine layer also helps in preventing desiccation of the pollen grain.
- The unique properties of sporopollenin make it an essential component of the exine layer, ensuring the successful pollination and reproduction of plants.
Therefore, Sporopollenin is primarily found in the Exine layer of pollen grains.
