multicellularity

Multicellularity refers to organisms composed of many cells, which work together to perform various functions. Unlike single-celled organisms, multicellular life forms, such as animals, plants, and fungi, have specialized cells that take on specific roles, like muscle cells for movement or nerve cells for communication. This division of labor allows for greater complexity and adaptability, enabling multicellular organisms to grow larger and develop advanced systems, such as organs and tissues. Overall, multicellularity is a key evolutionary step that contributes to the diversity and complexity of life on Earth.
