List and describe the characteristics of living systems. Answer: Cellular organization
All organisms consist of one or more cells. Often too tiny to see, cells carry out the basic
activities of living. Each cell is bounded by a membrane that separates it from its
surroundings.
Ordered complexity:
All living things are both complex and highly ordered. Your body is composed of many
different kinds of cells, each containing many complex molecular structures. Many
nonliving things may also be complex, but they do not exhibit this degree of ordered
complexity
Sensitivity:
All organisms respond to stimuli. Plants grow toward a source of light, and the pupils of
your eyes dilate when you walk into a dark room.
Growth, development, and reproduction:
All organisms are capable of growing and reproducing, and they all possess hereditary
molecules that are passed to their offspring, ensuring that the offspring are of the same
species.
Energy utilization:
All organisms take in energy and use it to perform many kinds of work. Every muscle in
your body is powered with energy you obtain from your diet.

,Homeostasis:
All organisms maintain relatively constant internal conditions that are different from their
environment, a process called homeostasis. For example, your body temperature
remains stable despite changes in outside temperatures.
Evolutionary adaptation:
All organisms interact with other organisms and the nonliving environment in ways that
influence their survival, and as a consequence, organisms evolve adaptations to their
environments.
