In endocytosis, transported substances are enclosed in vesicles formed from the plasma membrane, which do physically cross the plasma membrane. These vesicles then transport the substances into the cell.
The statement is incorrect. Molecules that are too large to be moved across a cell membrane are typically removed from the cell through exocytosis, where they are transported out of the cell in vesicles. Endocytosis is the process by which cells take in substances by engulfing them in vesicles, not removing them.
Exocytosis is the process by which cells release substances outside of the cell, while endocytosis is the process by which cells take in substances from outside the cell. In exocytosis, vesicles fuse with the cell membrane to release their contents, while in endocytosis, the cell membrane engulfs substances to bring them into the cell.
The process of taking in substances into a cell by surrounding them with the cell membrane is called endocytosis. It involves the formation of vesicles that engulf and transport the substances into the cell. Endocytosis is essential for nutrient uptake and cellular communication.
Endocytosis is the process by which cells take in substances by engulfing them with the cell membrane, forming vesicles that bring the substances into the cell. Exocytosis, on the other hand, is the process by which cells expel substances by fusing vesicles containing the substances with the cell membrane, releasing the substances outside the cell. Both processes involve the movement of materials across the cell membrane but in opposite directions.
The intake of small membrane vesicles from the extracellular fluid is called endocytosis. This process involves the engulfment of substances by the cell membrane to form vesicles that are then internalized into the cell.
