Synthesis
• the chemical
combining of
simple substances
to form more
complex
substances
Transport
• the process by which
substances move into
or out of cells or are
distributed within cells
Respiration
(cellular)
• the process of
releasing energy
(ATP) in a complex
series of chemical
reactions
Nutrition
Regulation
• the process by which • the control and
organism takes in food coordination of all
and breaks it down so
the life activities
it can be used for
metabolism
• involves ingestion,
digestion, and egestion
Growth
• the process by
which living
organisms
increase in size
Excretion
• the removal of
metabolic wastes
from an organism
Reproduction
• the process by
which living things
produce new
organisms of their
own kind
• not needed for the
survival of an
individual organism
Metabolism:
• the sum of all the
life functions
Homeostasis:
• the condition of maintaining a
constant internal environment in
an organism
Give examples when an organism is not
at homeostasis?
Movement
• Locomotion: ability to get from one place
to another
• Sessile (inability to move)
