ORGANISM
FUNGUS
Biologists can work
or in a

OUTSIDE
LABORATORY
While organisms are all , there are several characteristics they share in common.
DIVERSE
Living things are based
on a universal code.
GENETIC
The molecule, , stores the complex information organisms need to live, grow, and reproduce.
Information found in DNA is passed on from
to .
PARENT OFFSPRING
DNA
Living things
and develop.
GROW
Every organism has a
particular pattern of growth and development.
Living things
to their environment.
RESPOND
Organisms detect and respond to
from their environment. A
stimulus is a signal to which an
organism responds to.
STIMULI
Living things are made up of
CELLS!
Organisms are composed of one or more cells, which are the
units
considered to be alive.
SMALLEST
Living things obtain and use
material and .
ENERGY
To grow, develop, and reproduce, all organisms must take in materials and energy.
Living things go through a process called...
METABOLISM!
...which is the combination of
reactions through which an organism builds up or
materials.
CHEMICAL
BREAKS DOWN
"Groups of organisms
over time."
CHANGE
The of any group of organisms can change over time.
CHARACTERISTICS
The gradual process of change that occurs in groups of organisms is called:
EVOLUTION
Living things maintain a
environment.
STABLE
All organisms need to keep
their internal environment
stable, especially when external
environments can change. This is called
HOMEOSTASIS
Living things .
REPRODUCE
All organisms produce
new and
organisms.
SIMILAR
A Standard
Measurement System
Modern scientists use an expanded
system, called the International System of Units, or
abbreviated as .
METRIC
SI
SI Units are used to measure length, volume, mass,
, temperature, and time.
DENSITY
Using SI as the standard system of measurement allows scientists to data and communicate with each other about .
COMPARE
RESULTS
A metric system is a system of measurement based on the multiples of 10!
Most scientists use the metric system
when collecting and
performing experiments.
DATA
SEXUAL REPRODUCTION
– is when cells from two unite to form the first cell of a new organism.
ASEXUAL REPRODUCTION
– is when a organism produces offspring identical to itself.
