A cell or group of cells that are adjacent are known as neighbors.

Here's why:

* Adjacent means "next to" or "nearby."

* Cells are the basic building blocks of all living things.

* Neighboring cells often interact with each other, sharing information and resources, and contributing to the overall function of tissues and organs.

This concept is important in various fields, including:

* Biology: Understanding cell-to-cell communication is crucial for understanding tissue development, immune responses, and disease processes.

* Computer science: In computational models of biological systems, the concept of neighboring cells is essential for simulating the behavior of complex tissues and organs.
