Bulk transport across cell membrane is accomplished by

he correct answer is (D) All of these.

Bulk transport across cell membranes refers to the movement of large molecules or particles into or out of cells. This can be accomplished through:

– (A) Phagocytosis: the engulfment of solid particles, bacteria, or dead cells by the cell membrane, forming a vesicle called a phagosome.
– (B) Pinocytosis: the uptake of fluids, dissolved substances, or small particles by the cell membrane, forming a vesicle called an endosome.
– (C) Exocytosis (not extrusion): the release of mater
