1.
Identify what all organisms are
made up of.
• They are all composed of CELLS.
2. Describe the difference between
unicellular and multicellular organisms.
• Unicellular organisms consist of ONE cell.
• Multicellular organisms are composed of
MANY cells.
3.
Describe why energy is necessary
for survival.
• Necessary for cells to carry out
all life activities.
4. CONTRAST aerobic and anaerobic
respiration.
• Aerobic respiration - utilizes oxygen to
produce energy
• Anaerobic respiration - does not require
oxygen to produce energy
AEROBIC RESPIRATION
ANAEROBIC RESPIRATION
C6H12O6  6CO2 + 2ATP
Glucose
Carbon
dioxide
Energy
5. Identify what is necessary for
growth to occur.
• ENERGY
6.
Describe the process of synthesis.
• Chemically COMBINE simple or smaller
substances to form more complex
substances.
Small molecules

LARGE
MOLECULES
7. Identify an example of synthesis that
occurs in organisms and identify the substance
that is produced.
• Photosynthesis involves plants using light to
synthesize glucose.
• Protein synthesis involves cells combining
amino acids to produce large proteins.
Protein
synthesis
8. Why is nutrition necessary for
survival?
• Provides food for organism to produce
energy.
• Provides nutrients needed for many cell
processes.
Describe the difference between
the 2 types of nutrition.
• Autotrophic nutrition – organisms produce
their own food
• Heterotrophic nutrition – organisms cannot
produce their own SO THEY HAVE TO
INGEST FOOD
10. Identify the life process that
involves the absorption and circulation
of materials inside an organism.
• TRANSPORT
Locomotion
11. Contrast passive and active
transport.
• Passive transport – does not require energy
• Active transport – requires energy
12. Identify the types of wastes
that are excreted from the body.
• Cellular/Metabolic wastes
13. Identify 4 examples of metabolic
wastes excreted from the body.
•
•
•
•
Carbon dioixde
Water
Salts
Nitrogenous wastes
14. Identify a change in the
environment that organisms can detect.
• Stimuli
15. Describe the process of regulation.
• Controls and coordinates many life
activities.
16. Describe homeostasis.
• Maintaining a STABLE INTERNAL
ENVIORNMNET
17. Contrast asexual and sexual
reproduction.
• Asexual reproduction - involves only one
parent
• Sexual reproduction – involves 2 parents
18. Is reproduction necessary for
survival? Support your answer.
• No. It is necessary for the survival of a
species.
19. Describe what makes up an
organism’s metabolism.
• All life processes within cells of an
organism
20. Identify the factors that can
affect your metabolism
•
•
•
•
•
Gender
Age
Exercise
Diet
Drugs and alcohol

processes. Regulation
11. Increase in cell size or cell number. Growth
12. The ability to produce offspring.
Reproduction
13. Maintaining a stable internal environment.
Homeostasis
14. Type of respiration that uses oxygen.
Aerobic respiration
Let’s summarize…
1. Describe what your metabolism
consists of.
2. Describe some factors that affect a
person’s metabolism.
Which life function provides substances
that may be used by an organism for its
growth and for the repair of its tissue?
(1.) nutrition
(2.) excretion
(3.) regulation
(4.) reproduction
In an organism, the coordination of the
activities that maintain homeostasis in
a constantly changing environment is
a process known as
(1.) regulation
(2.) digestion
(3.) synthesis
(4.) respiration
The life process of transport in an
organism directly involves those
activities used to
(1.) release energy from food
(2.) produce cellular waste products
(3.) obtain and hydrolyze materials
(4.) absorb and distribute materials
The final result of the process of
respiration in animals is the
(1.) Release of oxygen as a waste product
(2.) Use of carbon dioxide to form sugars
(3.) Transfer of chemical energy to a more
usable form
(4.)Enzymatic decomposition of inorganic
raw materials
Which life function is most directly
involved in the control of the muscles
of an earthworm that is moving from
dry soil to moist soil?
(1.) Regulation
(2.)Transport
(3.) Nutrition
(4.) Excretion
The movement of an organism from one
place to another is known as
(1.) Circulation
(2.) Transport
(3.) Locomotion
(4.) Synthesis
