Pollen Allergy: A Pharmacological Insight
Pollen comprise of pollen grains, which are male gametophytes in coarse powder form of plants. These micro gametophytes will produce male gametes by moving from the androecium to the gynoecium. These pollen grains comprises of sporopollenin on the surface and takes the shape of a hard coat. This layer protects the gametophytes during the movement process. As the pollen reaches the surface of a compatible pistil (gynoecium), a pollen tube starts germinating which transfers the sperm to the ovule (female gametophyte). While the movement of the pollens, it may reach human body and can cause different forms of allergy based on the sensitivity of the host.
