Presentation Design  WHAT CHARACTERISTICS DO ALL LIVING ORGANISMS SHARE? GATHERING AND USING ENERGY One unique characteristic of living things is the ability to use energy and acquire materials to ensure survival. Presentation Design  Energy - ability of an organism to do work in order to move, grow and reproduce. Ex: Green Plants (photosynthesis) animals and humans (consuming other Presentation Design  Metabolism - sum of all chemical processes and energy changes happening inside the body of an organism. Ex: nutrient uptake nutrient processing waste elimination Presentation Design Nutrient Uptake and Processing Humans and animals - indirect; by ingesting food Green Plants - directly; sunlight to photosynthesis Fungi - by absorbing nutrients from dead or MAINTAINING INTERNAL BALANCE Excretion - process of removing unwanted waste products due to different metabolic processes. Presentation Design Examples of Metabolic Waste Products carbon dioxide water mineral salts nitrogenous waste products Presentation Design Organs Involved in Waste Elimination skin lungs liver kidneys large intestine urinary bladder Presentation Design MAINTAINING INTERNAL BALANCE Homeostasis - maintenance of the body’s internal balance to keep an organism alive. Presentation Design RESPONDING, ADAPTING AND EVOLVING Certain responsive processes allow organisms to react to changes in their surroundings in meaningful ways. Presentation Design Motility Most animals can move from one place to another by walking, flying, swimming, gliding, or jumping depending on their body and reason for locomotion. Presentation Design Irritability Ability of an organism to respond appropriately to external stimuli such as light, temperature, sound, pressure, food source, and etc. by making a reaction Presentation Design Individual Adaptation For living things to survive and perform normal functions, the ability to adjust to changes in the environment is a must. Presentation Design Evolutionary Adaptation Evolution - changes in the characteristics of a population over time. Evolutionary adaptation is a gradual or rapid change in body structure or behavior to better suit Presentation Design REPRODUCING AND CONTINUING LIFE Certain life properties relate to an increase in the size of the organism or increase in the number of organisms. Presentation Design Growth and Development Growth - an increase in size and volume by converting food to become a part of body cells. Development - stages starting from fertilization and ending Presentation Design Reproduction A process by which genetic information is passed on from one generation to another as organisms produce offspring.
