Which is the smallest of all levels of organization?

Cells
Cells are the most basic unit of life at the smallest level of organization. Cells can be prokaryotic (without nucleus) or eukaroyotic (with nucleus). The four categories of tissues are connective, muscles, epithelial, and nervous tissues. Organs are made of different types of tissues and perform complex functions.

### Which is the most complex level of organization?

The most complex level of organization, the human organism is composed of many organ systems that work together to perform the functions of an independent individual.

#### Which is the highest level of organ organization?

Figure 1.2.2 – Organ Systems of the Human Body: Organs that work together are grouped into organ systems. The organism level is the highest level of organization. An organism is a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life.
