  • What is Biology?

3
  • Biology is the study of life. Biology is a
    science, and follows the same principles and
    methods of other sciences.

4
Biology
  • Biology, from the level of the molecule to the
    level of the biosphere is connected to our daily
    life.
  • The study of Biology offers us a more profound
    understanding of ourselves and the planet, inturn
    it gives us a greater appreciation and value of
    life and our planet.

5
  • What is Life?

6
  • Life is the combination of physical and
    chemical processes that exist within an organism.
  • Eg. A Dog that breathes and one that doesnt.
  • Life is difficult to define but defining it helps
    us to differentiate between what is alive and
    what is not.

7
Characteristics of Living Things
  • Complex, organized structure consisting of
    organic molecules
  • Response to stimuli
  • Active maintenance of complex structure and
    internal environment (homeostasis)
  • Metabolism
  • Conversion of one form of energy to another
  • Growth
  • Reproduction using DNA keeping patterns
  • Have the capacity to evolve

8
Characteristics of Living Things
  • Living things have a metabolism, produce energy,
    respond to stimuli, adapt to environment, and
    maintain Homeostasis.
  • Homeostasis is the equilibrium of the internal
    environment of the organism with the external
    environment.
  • Eg. temperature in reptiles, hormones. The
    liberation of glucose by the liver to maintain
    the level of sugar in the blood.

9
Excercise
  • Is a computer virus a synthetic living being?
    Why?
  • Join in teams of three students to answer in a
    sheet of paper (include ID numbers)
  • Is the Doomsday machine a synthetic living
    being? Why?
  • Join in teams of three students to answer in the
    sheet of paper (include ID numbers)
  • What would be a synthetic living being? Why?
  • Join in teams of three students to answer in a
    sheet of paper (include ID numbers)

Branches of Biology
  • Zoology
  • Botany
  • Genetics
  • Ecology
  • Microbiology
  • Paleontology
  • Entomology
  • Physiology
  • Embryology
  • Anatomy
  • Bio-statistics
  • Cytology
  • Histology

11
Zoology
  • The study of Animals
  • Food crisis, Evolution, Disease

12
Botany
  • Study of Plants
  • Agriculture, Genetics, Food crisis

13
Genetics
  • The study of heredity in organisms.
  • Disease, Psychology, Evolution, Transgenic
    organisms.

14
Ecology
  • The study of the relation between living things
    and their environment.
  • Environmental Damage assessment, Cause and Effect
    relationships

15
Micology
  • The study of Fungus
  • Brain Function, Historical Diets, Medical/Health
    Benefits

16
Paleontology
  • Study of Fossils
  • Evolution, History, Climate Change

17
Physiology
  • The study of the systems in a living thing and
    the relation between systems.
  • Disease, Treatment (Medicines), Athletics,
    Extreme sports

18
Embryology
  • The study of organisms in the womb, or the study
    of embryos.
  • Disease, Disfigurement, Maximizing the health of
    the child

19
Anatomy
  • The study of structure
  • Prosthetics, Reconstructive Surgery, Aesthetic
    Surgery, Evolutionary Patterns

20
Citology
  • The study of cells.
  • Drug Uptake, Disease (Cancer etc.), Evolution,
    Cell Recognition

21
Histology
  • The study of tissue
  • Disease, Differentiation, Cell recognition,
    cancer identification.

22
Revolutions in Biology
  • During a good deal of time Biology has been
    stagnant, however the 19th and 20th centuries
    were important for the revolution of science
    during this time these important discovers about
    the history of biology were made.
  • DNA DISCOVERY
  • Genetic Manipulation
  • Human Genome
  • Cloning, Test Tube Baby

23
Revolution in Biology
  • Nutrition control of pests
  • Identification of 2 million living things
  • Origin of life
  • Classification of diverse forms of life
  • New pathogens such as HIV
  • More efficient and complicated microscopes

24
Revolution in Biology
  • Advances in the field of Medicine
  • Vaccines
  • Antibiotics
  • New illnesses and cures for others.

25
Areas of Application
  • Medicine antibiotics, new medicines
  • Food Sciences new foods for animals
  • Agriculture - Pesticides (insecticides,
    herbicides and biological control agents).
  • Environment contamination of air, water y soil.
    Recycling.
  • Investigation - genetics, botany, zoology, etc.
  • Food Science More resilient seeds.
