Endocytosis:This is a process where cells absorb material (like proteins) from outside by engulfing it with their cell membrane, forming a vesicle.
Exocytosis:This is the opposite of endocytosis. It's when cells expel waste or secrete substances contained in vesicles out into their environment.
Lysosome:These are special types of vesicles that contain enzymes to break down waste materials and cellular debris inside the cell.
