Solution
The correct option is A Sporogenous tissue Pollen grains develop from sporogenous tissue in angiosperms. In angiosperms, double fertilization takes place. Pollen grains develop in the anthers of the staminae. At the inner side of each loculus a layer of large, rectangular cells, the tapetum can be found. The tapetum serves for the nutrition of the developing pollen.
