A pollen grain in angiosperm at the time of dehiscence from an anther could be 2-celled or 3-celled. Explain. How are the cells placed within the pollen grain when shed at a 2-celled stage ?
In majority angiosperms, pollens are released in 2-celled stage whereas in other species, the generative cell divides into 2 male gametes & forms 3-celled stage. When the pollen grain is shed at 2-celled stage - it has two unequal cells - bigger vegetative cell and smaller generative cell.
