This is especially true in biology, as classifying and organizing the intrinsic attributes of living things is critical to understanding the world around us. The Bacteria are another quite different group of single-celled organisms without nuclei (Figure 2. Multicellular Organisms Tissues – groups of similar types of cells in multicellular organisms that work together to carry out specific tasks. You will understand the basic classification system of life and how this system reflects evolutionary relationships. It is also important to realize that humans and other living organisms interact with one another and the environment as the hierarchy of biological organization continues upward from organisms to populations, communities, ecosystems, and the biosphere. For example, the North American blue jay is known uniquely as Cyanocitta cristata. Tissue is an organizational level composed of similarly specialized cells that carry out specific functions. In the human body, the eleven organ systems are categorized by their structure and function. In fact, most organs contribute to more than one system.
