The process by which a cell ingests extracellular fluid and its dissolved solutes is called pinocytosis.

Here's a step-by-step explanation:

1. The cell membrane invaginates, forming a small pocket around the extracellular fluid and its dissolved solutes.
2. This pocket deepens and eventually pinches off from the cell membrane, forming a vesicle within the cell. This vesicle contains the ingested fluid and solutes.
3. The vesicle then moves into the cell, where the fluid and solutes can be processed and used by the cell.
4. This process is a type of endocytosis, specifically called pinocytosis, which is often referred to as "cell drinking".
