* Single-celled organisms have to perform all life functions within their single cell. This means they are responsible for everything like obtaining nutrients, eliminating waste, and reproducing all within their one cell.
* Multicellular organisms, on the other hand, have specialized cells that perform specific tasks. This means different types of cells work together to create tissues and organs, each with its own function. For example, muscle cells contract for movement, nerve cells transmit signals, and digestive cells break down food.
This specialization in multicellular organisms allows for greater complexity and efficiency in carrying out life functions.
