Is a cell a complex structure?
A cell is so complex that even the high level of technology attained today cannot produce one. No effort to create an artificial cell has ever met with success.
Which of the following is the least complex level of organization in living things?
The simplest level of organization for living things is a single organelle, which is composed of aggregates of macromolecules.
What is complexity in higher organisms?
Complexity give rise to bigger size of higher organism which in turn lead to requirement of more space energy and environmental resources than single cell organisms. 3. There is increase metabolic rate which consumes more food.

What is the most complex cell?
Eukaryotic cells are much more complicated than those of prokaryotes. They are packed with a fascinating array of subcellular structures that play important roles in energy balance metabolism and gene expression.
What is a complex organism?
A complex organism contains multiple organ systems with different functions. Multiple organisms of a single species may form a group, called a population. Many populations of different species form diverse communities, and communities that share the same geographical space are part of a larger ecosystem.
