What are the different levels of organization?
An organism is made up of four levels of organization: cells, tissues, organs, and organ systems.

What is the order of cell organization?
From simplest to most complex, the proper levels of organization in multicellular organisms are: Page 2 The levels of biological organization in order from smallest to largest are: atom → molecule → macromolecule → organelle → cell → tissue → organ → organ system → whole organism.
What are the levels of organization in a human body?
It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms and biosphere (Figure 1.3).
What are the levels of complexity?
Notes about each of these levels of complexity:
- Elements. Knowledge of basic science includes the distinction between atoms and molecules, and elements, mixtures and compounds.
- Molecules. The size of molecules varies enormously depending on the type of molecule.
- Organelles.
- Cells.
- Tissues.
- Organs.
- Organ Systems.
- Organism.
How do the levels of organization become more complex?
Cells can then be organized into tissues, which form organs, and organs can be grouped into organ systems, which are built into entire organisms—including humans like you. Organisms are units that can form populations, and then biospheres, which go on to make up even greater levels of complexity.
What are the levels of organization in the nervous system?
The human central nervous system contains the brain, spinal cord, and retina. The peripheral nervous system consists of sensory neurons, clusters of neurons called ganglia, and nerves connecting them to each other and to the central nervous system.
