The process where a cell uses a vesicle to move molecules into the cell is called endocytosis.

Here's a breakdown:

* Endocytosis: This is the process where the cell membrane folds inward, engulfing the molecules and forming a vesicle around them. This vesicle then pinches off and moves the molecules into the cytoplasm of the cell.

There are three main types of endocytosis:

* Phagocytosis: This is the process where the cell engulfs large particles, like bacteria or cellular debris.

* Pinocytosis: This process involves taking in fluids and small dissolved molecules.

* Receptor-mediated endocytosis: This is a more specific process where the cell takes in specific molecules by binding to receptors on the cell surface.
