Read the following text and answer the following questions on the basis of the same: A typical anther is bilobed. It is a tetragonal structure consisting of four microsporangia. These microsporangia form pollen sac which on maturity gets filled with a pollen grains. Pollen grains represent the male gametophytes, their cell wall is very hard. Pollen grains of many species cause severe allergies which cause various diseases in human beings. Assertion (A) : The innermost layer of microsporangium is called tapetum. Reason (R) : Tapetum nourishes the develop into pollen grains.
