The cellular component assembly that is part of the initial shaping of the component during its developmental progression. The process whose specific outcome is the progression of the pollen grain over time, from its formation to the mature structure. The process begins with the meiosis of the microsporocyte to form four haploid microspores. The nucleus of each microspore then divides by mitosis to form a two-celled organism, the pollen grain, that contains a tube cell as well as a smaller generative cell. The pollen grain is surrounded by an elaborate cell wall. In some species, the generative cell immediately divides again to give a pair of sperm cells. In most flowering plants, however this division takes place later, in the tube that develops when a pollen grain germinates. The chemical reactions and pathways resulting in the formation of sporopollenin, a primary constituent of the pollen exine layer. A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of external structures that lie outside the plasma membrane and surround the entire cell. The formation of reticulate pollen wall pattern consisting of two layers, exine and intine. The formation of the pollen exine. The reticulate pollen wall pattern consists of two layers, exine and intine.
