Helps maintain genetic variability in a population
Sefl incompatibility is a mechanisms in plants that help in preventing inbreeding and allows outcrossing. This is controlled genetically by one or more multi allelic loci and usually relies on the series of complex cellular process and interaction between pollen and the pistil. There are various types of self incompatibility used by angiosperm. In this process autogamy is prevented and allogamy is produced.

Answer/Explanation:
First, the polypeptides are synthesised and folded in the endoplasmic reticulum, which is a series of folded membranes.
Then, the polypeptide is packaged into vesicles and moved into the Golgi apparatus, which are stacks of flattened sacs. At the Golgi apparatus, the polypeptide is modified, forming the final structure of the protein. The proteins are then packaged in to vesicles to be transported to their final destination outside of the cell.
The proteins are delivered outside the cell in vesicles via a process called exocytosis. The vesicles reach the membrane, fuse with the membrane, and are then delivered outside the cell.
