2
Life Functions

• Nutrition
• Respiration
• Reproduction
• Transport/Circulation
• Excretion
• Movement
• Regulation/Coordination
• Homeostasis

3
Inorganic

• What type of material would be found in this car?
  

4
Inorganic

• Inorganic compounds are found in Living organisms
  and do not have carbon hydrogen combinations.
• Iron (Fe)
• Copper (Cu)
• Salt (NaCl)
• Carbon dioxide (CO2)
• Water (H20)

5
Organic

• Organic compounds have carbon and hydrogen
  elements in them.
• Ex.
• Proteins
• Carbohydrates
• Nucleic acids (DNA)
• Fats

6
Which compound is organic

• NaCl
• C6H12O6
• Fe (iron)
• H2O

7
Nutrition

• The process in which food is taken in (ingested)
  then broken down into smaller molecules
  (digested) which can be absorbed, wastes are
  (egested).

8
Ingestion

• Taking in nutrients, ways differ depending on
  organism.

9
Digestion

• Large molecules are broken into smaller ones so
  that they can be absorbed

• Humans have 1 stomach
• Cows have 4 stomachs
• Ameoba have none they use enzymes

10
Respiration

• Chemical energy that you eat is converted to a
  useable form by your body.
• Glucose goes into your cells and is absorbed by
  your mitochondria via the krebs cycle. The oxygen
  you breath causes electrons to move across the
  electron transport chain to generate ATP, which
  you use to power your body.

11
Two types of Respiration

• Aerobic The process of aerobic respiration uses
  oxygen to produce ATP. Chemical formula is
  Glucose
  Oxygen ?ATP (energy) Carbon dioxide Water
• Anaerobic respiration Uses no oxygen to produce
  ATP.
• Glucose (Broken down to) ?Energy (ATP)
  Ethanol Carbon dioxide (CO2)
• Glucose (Broken down to) ?Energy (ATP)
  Lactic acid

12
Reproduction

• Asexual 1 parent an organism splits to make
  another identical copy, a clone
• Sexual 2 parents, sperm and egg produce
  offspring that are diverse

13
Transport/Circulation

• Materials are moved through the organism. Humans
  have a circulatory system. Single celled
  organisms move fluid via cyclosis.

14
Excretion

• Removal of cellular wastes NOT FECES

15
Excretory Organs

• Lungs Remove CO2
• Liver Removes toxins, dead cells
• Skin Removes urea
• Kidney Removes urea (nitrogen wastes)

16
Movement

• Ability of an organism to move
• Plants move by enzymes

• Paramecium have cilia

• Ameoba have pseudopods

17
Survival strategies of movement/locomotion

• Find food
• Find shelter
• Regulate body temp, move to shade when hot
• Move away from predators
• Find a mate

18
EndoSkeletons

• Endoskeletons a calcium, magnesium, deposit left
  by a cell to form a bone. Grows due to pressure
  placed on it

19
ExoSkeletons

• Exoskeleton outside skeleton that protects
  insects and crustaceans. Made of a protein called
  chitin.

20
Regulation/Coordination

• Control of all life activities. Includes the
  nervous system and the endocrine system (hormones)

21
Immunity

• White blood cells destroy outside invaders.
  Viruses, bacteria, foreign\ proteins (pollen)

22
Synthesis

• Simple molecules are combined to form complex
  molecules such as carbs, protein and fats

23
Growth

• A cell gets larger
• A cell reproduces

24
Metabolism

• Cells capture and store energy and release that
  energy in appropriate amounts to perform all your
  life functions.

25
Homeostasis

• Regulates the body through all of the body
  systems. If you are hot your body cools off by
  sweating. If you are cold you shiver where your
  muscles spasm to cause friction which creates
  heat.
