2. Life Science Characteristics of Living Things

3. 5 Kingdoms of Living Things Animals (humans, elephants, octopus, birds) Plants (trees, grass, weeds, shrubs, flowers) Fungi (mushrooms, molds, yeast) Protist (amoeba, paramecium, euglena) Monera (bacteria)

4. Characteristics of Living Things 1) Are made up of cells 2) Can move 3) Can perform complex chemical activities 4) Grow and develop 5) Respond to their environment 6) Reproduce

5. Living Things are Made of Cells Cells are the basic building blocks of living things Cells come only from other cells Single celled called (unicellular) Many celled called (multi-cellular)

6. Living Things Can Move Why Move? Need to move to find food and shelter Need to avoid danger Need to search for a mate Plants move to get more sun/water

7. Living Things Perform Complex Chemical Activities Ingestion-taking in food (plants make food) Digestion- food is broken down into simpler substances Respiration-use oxygen to produce energy Excretion-process of getting rid of wastes

8. Living Things Grow and Develop Growth - gaining cells Development-part of growth process when dramatic changes take place Metamorphosis Life span-maximum length of time a species can be expected to live

9. Living Things Respond to their Environment Stimulus-any change in the environment that produces a response (smells, noise, light, water,) Response-action, movement, or change in behavior (blinking)

10. Living Things Need to Reproduce Living things will become extinct if they do not reproduce 2 types (sexual/asexual) Sexual - 2 parents Asexual - 1 parent
