Life Characteristics Flashcards
What are all the characteristics of life
Cells Organization Growth/development Reproduction Responses to stimuli Requires energy Maintains homeostasis Adaptation
Cells definition
Basic component of all living things
One cell
Unicellular
Many cells
Multicellular
Organization of what makes up what
Cells make up tissues
Tissues make up organs
Organs make up systems
Systems carry out bodily functions
Definition of growth
Increase in mass to an organism, and in many organisms, the formation of new cells and structures
Reproduction definition
Production of offspring which must occur in order for species to continue
Species definition
A group of organisms that can mate with one another to produce FERTILE offspring
Stimulus
A signal to which an organism reacts
Response
Reaction to stimuli
What is energy used for
Carrying out essential biological procedures
Autotrophic
Produces own food (light or chemicals
Heterotrophic
Consumes food
Decomposer
Breaks down dead materials for food
Maintains homeostasis
Constant maintenance of an organisms internal environment
Homeostasis
When a change in the internal environment occurs, processes within the organism work to regain the normal environment state
Adaptation
Any inherited characteristics that result from changes to a species over time. These characteristics are favorable for species and allows them to pass their genes to their offspring
Animals panting
Homeostasis
When you get a temp and your body cools down
Homeostasis
Growing more hair
Adaptation
Putting on a coat
Response
You shiver because it’s cold
Homeostasis
