Final answer:
Large solid particles enter a cell through endocytosis, which is a cellular process where the cell engulfs and takes in materials from the external environment
Step-by-step explanation:
Large solid particles can enter a cell through a process called endocytosis. Endocytosis is a cellular process where the cell engulfs and takes in materials from the external environment. There are three types of endocytosis: phagocytosis, pinocytosis, and receptor-mediated endocytosis. In phagocytosis, the cell extends its membrane around the particle and forms a vesicle, which is then transported into the cell. This process is used by immune cells to engulf and destroy pathogens. In pinocytosis, the cell forms invaginations in its membrane and engulfs extracellular fluid along with any particles present in it. Receptor-mediated endocytosis involves the use of specific receptors on the cell membrane to recognize and bind to particular molecules. When the receptor binds to a molecule, a vesicle is formed and transported into the cell.
