CHARACTERISTICS OF ALL LIVING THINGS

• Made of cells (can be unicellular or multicellular)• Contain DNA (control cell activities)• Grow…increase # of cells; get bigger• Develop…changes an individ goes thru during life• Respond to stimuli (R: way we react; S: causes rxn)• Need energy (to do work; carry out life processes)• Reproduce themselves (to continue the species)• Have a life span (eventually die)• Adapt to their environment (change to survive)• Evolve (change in a species)• Maintain homeostasis (state of balance)

#1

OTHER IMP’T VOCAB

• # 2 ORGANISM…a complete living thing• UNICELLULAR…made of one cell• MULTICELLUAR…made of many cells• #4 SPECIES…group of organisms that look similar

and can reproduce to produce fertile offspring• # 8 HOMEOSTASIS…a steady balance• METABOLISM…all activities that an organism

carries out to keep it alive

• # 3: DNA is found in every cell and provides all the information needed to control the organism’s life processes

• # 5: REPRODUCTION is necessary for a species to survive…if species do not make more of themselves…their species will die out

• # 9: all living things need energy to carry out the processes of life (metabolism)…organisms obtain energy from the sun or food

# 6 GROWTH VS. DEVELOPMENT• GROWTH…

increase in # of cellsincrease in size

• DEVELOPMENT…Changes an individual goes through during life cycle

physicalemotionalphysiological

# 7 STIMULUS VS. RESPONSE• STIMULUS…– Causes a reaction– EX: loud noise,

temperature

• RESPONSE…– The way an organism

reacts– EX: jumps, shivers

# 10 organisms must adapt in order to survive as the environment changes

• ADAPTATIONchange to be better suited

in their environment

EX: white fur to blend in the

arctic regionsWebbed feet for swimming

• EVOLUTIONChanges in a species overLong periods of time
