cellular organization

Cellular organization refers to how living organisms are structured at the microscopic level, specifically through cells, which are the basic units of life. In multicellular organisms, cells group together to form tissues, which then organize into organs, and those organs work together in systems. For instance, muscle cells form muscle tissue, which combines to make muscles (organs) that aid movement. In unicellular organisms, like bacteria, a single cell carries out all life functions. Overall, cellular organization is essential for the complexity and functionality of life forms, allowing them to grow, adapt, and thrive.
