Cells that have receptors for a particular hormone are called

Explanation:
When a hormone acts, only cells that have receptors for that hormone respond. Those cells are called target cells. The receptor on the cell is what makes it responsive—binding the hormone starts a cascade inside the cell that changes its activity. If a cell lacks the receptor for that hormone, it won’t respond, so it isn’t a target for that hormone. Receptors are the binding proteins, but the label for the responsive cells is target cells. For example, insulin affects liver, muscle, and adipose tissue because those cells have insulin receptors, making them insulin’s target cells.
