AboutParas Anand Expertise I have studied molecular biology & cell biology. I would be happy to answer your general questions on cells, their organelles, membranes and host-pathogen interaction. I will not answer questions on basic biology.
Question When vesicles from the Golgi apparatus deliver their contents to the exterior of the cell, they add their membranes to the plasma membrane. The plasma membrane does not increase in size, because
Answer Just as many processes add membrane to the PM, similarly membrane is also taken from the PM and added to the organelles inside the cell e.g. endocytosis. Therefore there is no net increase in PM. This is also required for cell equilibrium.
