Characteristics of Living Things Cell & Cell Organization Reproduction Growth Uses Energy Maintains Homeostasis Transport Materials Excretion Adapt & Evolve

1. Cell and Cell Organization Cells are the basic unit of life Cells of the same type make up tissues Cells Tissues Organs  Organ System Organism

2. Reproduction -Producing offspring

Do you need to reproduce to be alive????

3. Growth & Development A series of metabolic changes from an embryonic state to a mature state

Energy is called ATP 4. Energy We break down glucose to make energy, which is called cellular respiration

5. Homeostasis Maintaining the internal balance. Responding to the external and internal changes EX: sweating when hot

6. Transport Materials An organism absorbs and distributes materials Humans absorb nutrients from food in their digestive tract

7. Excretion Wastes from metabolism are removed i. e 7. Excretion Wastes from metabolism are removed i.e. your kidneys filter your blood to remove wastes, which is excreted as urine

8. Adapt & Evolve Adaptation: a structure or behavior that allows an organism to respond to stimuli and better suited to survive in an environment. Evolution: The gradual change over time
