Explore Homeostatic Properties
One of the key features of life is the ability of an organism to respond to its internal and external environment. The internal environment of an organism, whether unicellular or multicellular, must be held within a tolerable range to maintain function. The term homeostasis describes an organism's ability to maintain a relatively consistent internal environment.
Recall that eukaryotic cells are structurally more complex than prokaryotic cells. These cells contain a number of membrane-bound organelles that carry out specific functions. The organelles must work in concert with one another to maintain homeostasis within the cell. Nevertheless, it is rare that animal cells function as individual units. Cells with similar functions form tissues. These tissues then combine to form organs. Several organs may function together to form an organ system. In multicellular organisms, maintenance of homeostasis begins at the cellular level and extends to tissues, organs, and organ systems……….. Continue
