All groups of living organisms share several key characteristics or functions: movements, respiration, sensitivity, growth, reproduction and excretion. These include cellular organization, reproduction, growth and development, regulation, nutrition, locomotion, excretion, and respiration. Key characteristics of animals include the following: Scientists need scientific vocabulary to communicate effectively. Lack cell membrane and cell wall. Learn these seven characteristics of living organisms.They form the basis of the study of Biology. As cells grow, expand and divide, the creature becomes larger over time.
