Solution
The correct option is C Pollen grains are formed
Pollen grains develop in the anthers of the staminae. In the anthers mostly four, but sometimes only two loculi are present. In the loculi sporogenic tissue can be found from which pollen develop. At the inner side of each loculus a layer of large, rectangular cells, the tapetum can be formed. The tapetum serves for the nutrition of the developing pollen, the deposition of cell wall material in the outer part of the pollen grain and other compounds in and over the wall. First, the pollen mother cells are formed, which become spores by a meiotic division. The meiosis involves two divisions, which lead to the formation of four daughter cells the spores. These are the pollen grains which are haploid in nature, produced as a result of meiosis which is also called as reductional division.
