Solution
The process by which a cell ingests extracellular fluid and its dissolved solutes is called pinocytosis.
Here's a step-by-step explanation:
- The cell surface indents, forming a small pocket.
- The pocket deepens and seals off, forming a vesicle filled with extracellular fluid and its dissolved solutes.
- The vesicle detaches from the cell surface and moves into the cell, where the solutes can be released and used by the cell.
This process is a type of endocytosis, specifically called pinocytosis, which is often referred to as "cell drinking".
