The Characteristics of
Living Things

what is Life?
What is Biology?
How do you determine if something is living or not?
Objective

Characteristic #3: Response to Environment
Characteristics of Living Things
Characteristic #4: Homeostasis
Characteristics of Living Things
Characteristic #5: Metabolism
Characteristics of Living Things
Characteristic #6: Growth
Characteristics of Living Things
Characteristic #7: Reproduce
All living things are made up of at least one cell
Unicellular: one-celled organisms (bacteria)
Multicellular: many-celled organisms (plants and animals)
Organisms are able to respond to physical or chemical changes in the internal or external environment
Ex/ when a cat feels threatened they puff up and arch their back
Organisms have mechanisms that keep internal conditions within a specific range, despite changes in the environment
Ex: our bodies sweat when our body temperature is above a specific range
Organisms take in energy from their environment, and convert it for repair, movement, and growth.
Characteristics of Living Things
Characteristic #1: Organization
High degree of order within an organism's internal and external parts and in its interactions with its environment.
Characteristics of Living Things
Characteristic #8: Change Through Time
Organisms become larger through cell division and enlargement
Development: organisms become a mature adult as cells divide and differentiate (specialize). Allowing different types of cells to perform different necessary actions for the adult organism
Organisms can create offspring similar to themselves through heredity, the ability to pass traits on through genes
DNA: (deoxyribonucleic acid) the large molecule used to store genetic data
Populations of organisms change or evolve over time to adapt to an ever changing world
ex: compare a rock to an owl
rock has a specific shape but is irregular and different rocks of the same type have different shapes
Owl is highly organized and owls of the same species have the same parts arragnged in nearly the same way and interact with environment the same way.
Autotrophic: Organisms that create their own food (ex. Plants)
Heterotrophic: Organisms that are unable to create their own food. They must consume other living things as a food source (ex. animals)
