Characteristics of Life
10
Life.....

• What is it?
• Where did it come from?
• Why is it here?
• How does it work?
• All questions that biologists try to answer .....

11
Biology is the Science of Life

• What is LIFE??
• Life is what living things do!!

12
What is Life ? ORGANIZATION

• Living things are complex and highly organized
• Pattern of structures within structures
• Defined levels

13
What is Life ? ENERGY USE AND METABOLISM

• Living things are capable of energy
  transformations
• METABOLISM
• Anabolism or Catabolism
• Build, Repair, Break down,Reproduce, Transport
• Energy transformations
• - Endergonic or Exergonic

14
What is Life? MAINTENANCE OF INTERNAL CONSTANCY

• Homeostasis
• same state constancy
• Control concentration of salts, sugar, and water
  in cell/organism
• Temperature maintenance
• pH maintenance

15
What is Life? GROWTH, REPRODUCTION,
DEVELOPMENT

• Growth - increase in cell size
• and / or cell number
• Reproduction - increase in number of organisms
  can be sexual or asexual
• Development - series of orderly changes within
  organism

16
Mr. Mrs. Mt. Gorilla proudly announce
17
What is Life ? IRRITABILITY AND ADAPTATION

• Living things respond to stimuli from the
  external and internal environments
• - Irritability is an immediate response
• - An adaptation is a response developed over
  time
• Both essential to survival

18
Some Characteristics of Life

• Orderliness, organization
• Energy Use and Metabolism
• Regulation, coordination
• Reproduction, Growth
• Sensitivity, responsiveness
