The intine layer, which is located between the exine of the pollen wall and the cell membrane, is essential for the maturation of the pollen grain and
Where is the intine found?
The free amino-acids, proteins and enzymes contained in pollen grains are found in the cytoplasm and in the inner (intine) and outer (exine) wall of the pollen grain.
What is intine in pollen grain?
The intine is composed of cellulose and hemicellulose and the exine is made up of sporopollenin that is resistant against high temperature, alkali, strong acid, and enzyme. Therefore, we concluded that the intine layer of the pollen grains consist of both pectin and cellulose.
