Characteristics of Living Things What all organisms have

Characteristics of Living Things What all organisms have in common

Characteristics of Living Things All ORGANISMS share common characteristics. • Made of Cells • Chemicals of Life (Genetic Material) • Reproduce • Grow and Develop • Obtain and Use Energy • Respond to their Environment • Maintain Homeostasis • As a group, Evolve

Vocabulary Organisms: a living thing Abiotic Biotic • Non-living things in the environment • Examples: water, soil, sunlight, oxygen, carbon dioxide May have some, but not all of the characteristics of living things • Living • Organisms: living things in the environment • Have all of the characteristics of life

Made of Cells • Cell: basic unit of structure and function in an organism • Unicellular: made up of one cell (ex. Bacteria) • Multicellular: many cells (ex. Human)

Chemicals of Life ▫ The cells of living things are all made of chemicals ▫ Cells are made up mostly of water

Reproduce ▫ Produce offspring that are similar to the parents ▫ Asexual (1 parent ) and sexual (2 parents) ▫ Make more of a species

Asexual

Sexual

Growth and Development • Growth: the process of getting larger • Development: a process of change that occurs throughout an organisms lifetime

Obtain and Use Energy • Organisms require energy to go through life’s processes • Need energy for growth, repair and daily activities • Autotrophs ▫ “self-feeder” ▫ Make and use own food ▫ Example: plants • Heterotroph ▫ “other-feeders” ▫ Must get energy by eating autotrophs or other heterotrophs ▫ Examples: animals, mushrooms, slime molds

Energy

Respond to the Environment • Stimulus: something that causes an organism to react ▫ Ex. Changes in light, temperature, light and sound • Response: an action or change in behavior ▫ Ex. Movement, sweating, blinking

Homeostasis • Maintaining stable internal condition �Example: sweating to cool your body down �Example: shivering to warm up �Without homeostasis organisms will be sick or die

Evolution • Evolution: A gradual change in a species overtime

Needs of Living Things • Energy • Water • Living Space • Stable internal Conditions (Homeostasis)

Vocab • Transportation: Movement of materials • Excretion: removal of waste materials from a cell (urine, sweat) • Metabolism: all chemical reactions in an organism • Nutrition: body takes in and uses food • Synthesis: combinations of parts to make a whole
