Question

by which method of transport can large substances enter a cell?
endocytosis
facilitated diffusion
exocytosis
osmosis

Explanation:

• Endocytosis: It is a process where the cell membrane engulfs large substances (such as macromolecules, bacteria, or other cells) and forms vesicles to bring them into the cell.
• Facilitated diffusion: This is a passive transport process that helps move small - to - medium - sized molecules (such as glucose, amino acids) across the cell membrane with the help of transport proteins. It is not for large substances.
• Exocytosis: This is the opposite of endocytosis. It is used to release substances (such as hormones, waste products) from the cell.
• Osmosis: It is the movement of water molecules across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. It is related to water movement, not large substance transport.

Answer:

endocytosis
