What is the name for a complex organized group of organisms?
Tissues form organs, and several organs may have interrelated functions in a cohesive organ system, such as the digestive system. A complex organism contains multiple organ systems with different functions. Multiple organisms of a single species may form a group, called a population.
Why cells are highly complex and organized?
Cells Are Highly Complex and Organized: There is a great deal of consistency at every level. Each type of cell has a consistent appearance when viewed under a high-powered electron microscope; that is, its organelles have a particular shape and location, from one individual of a species to another.
