Prime Time: • On your handout, list at least 4 characteristics of all living things. (What do all living things have in common?) • As a group at your table, try to come up with at least three characteristics you all agree on.
6 Characteristics(Copy these onto your paper) • Cellular Organization • Reproduction • Respond to Environment • Grow and Develop • Energy Use • Chemicals of Life
1. Cellular Organization • All organisms are made of one or more cells • unicellular– single celled organisms such as bacteria (most numerous organisms on Earth) • multicellular – organisms made of many cells that are specialized for certain tasks
2. Reproduction • The ability to produce offspring or reproduce – offspring are usually similar to the parents
3. Respond to Environment • All organisms react to changes in their environment • stimulus – the change in the organism’s environment that causes the organism to react • response – an action or change in behavior • Organisms also adjust to changes in their internal environment • homeostasis – the maintenance of stable internal conditions
4. Growth and Development • growth – becoming larger – increase in size • development – becoming more complex – changes that occur as organisms grow • Life span – all organisms have a finite life span
5. Energy Use • All organisms need energy • Main source of energy for all organisms is the sun.
6. Chemicals of Life • Cells of all living things are made of chemicals. • Water-required for all cell processes • Carbohydrates (energy) • Proteins –building materials • Lipids (fats)-building materials • Nucleic Acids (DNA)
Basic Needs • Water • Food • Oxygen • Shelter (Habitat) • 2 ways for organisms to get food (energy) • autotrophs – organisms that make their own food – ex: plants • heterotrophs – organisms that can’t make their own food so they feed on others that can
6 Characteristics Review Cont. 2. Write the example, then using the 6 characteristics write the correct choice for each example. • Eat dinner every day. • Lipids are needed for cell structures. • Your dog now weighs 25 pounds. • All living things are made of these. • A plant bends toward the light • Your horse just had a foal.
6 Characteristics Review • On your clean piece of paper (with heading 3 on it) list the 6 characteristics of living things. (NO NOTES, NEIGHBORS)
6 Characteristics(Correct your answers.) • Energy Use • Chemicals of Life • Grow • Cellular Organization • Respond to Environment • Reproduction
