The rough endoplasmic reticulum is the site of protein synthesis and the smooth endoplasmic reticulum is the site of lipid synthesis. what is the third compartment of the endomembrane system and what is that compartment's function? a. golgi apparatus; finishes the processing of the proteins and sorts them for export out of the cell b. lysosomes; sacs which export the proteins and lipids out of the cell c. ribosomes; the place of protein transcription d. vesicles; packages of proteins surrounded by cell membranes that sort the proteins and lipids for packaging e. none of the above is correct.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
