Explanation:
Detailed explanation-1: -The ER has two major functions: Transport: Molecules, such as proteins, can move from place to place inside the ER, much like on an intracellular highway. Synthesis: Ribosomes that are attached to ER, similar to unattached ribosomes, make proteins. Lipids are also produced in the ER.
Detailed explanation-2: -Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell, draws the contents in, and forms an intracellular vesicle called an endosome. This vesicle travels through the cell, and its contents are digested as it merges with vesicles containing enzymes from the Golgi.
