Characteristics of Living Things At your table grouping, use your whiteboard to record your thoughts on the following questions: 1. What are characteristics or features of living things? 2. What are some examples of living things? 3. What are some examples of non-living things?
Living things… 1. Are organized and made of cells Example: Organism organ systems organs tissue cell organelles
• 2. Reproduce • Asexual reproduction: one parent, offspring are identical • Sexual reproduction: two parents, offspring are different (genetically)
• 3. Grow and develop • Grow…get larger • Develop…structural change (puberty, life cycles of insects/frogs)
• 4. Respond to their surroundings • Response to stimulus • Homeostasis: An organism maintains and keeps the same conditions in order to survive • Example: A person sweats (response) when they’re hot (stimulus) to maintain the constant body temperature needed to stay alive
5. Require energy • Autotroph: makes it’s own energy, like plants doing photosynthesis • Heterotroph: has to consume or eat things to get energy
6. Adapt and evolve • Adapt: Anything that enables an organism to survive • Evolve: Changes in characteristics of an entire species over a long, long time
