Text SolutionText solutionverified iconVerified

Each microspore or pollen is having a two layered wall. Outer layer is thick tough cuticularised called exine, which is chiefly composed of a material called 'sporopollenin'. Inner layer is thin, delicate and smooth called intine, which is made of pectocellulose. Exine is not uniform but is thin at one or more places in the form of germ pores. Whereas intine made of pectocellulose covers the entire surface of pollen grains.
