The process by which a cell ingests extracellular fluid and its dissolved solutes is known as 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. It's a way for cells to ingest fluids and small particles, as opposed to larger particles which would be ingested by phagocytosis.
