What is Biology?

• Work in assigned groups of four.
• Come up with as many words that start with the
  prefix Bio you have 10 minutes.
• GO!!!!!!!!!!!!

life.

Biological Perspectives

• Global to Microscopic
• Biosphere The living portions of the Earth,
  including land and sea. Essentially the skin
  of the earth which is interconnected and alive!
• Ecosystems All the biotic and abiotic components
  that make up a community of living organisms.
  Each has its unique characteristics.

13

• -- Organisms A living entity that carries out
  specific functions, both internal and external,
  to survive.
• -- Cells All living creatures are composed of
  cells.
• -- All living creatures pass on hereditary traits
  through a unique set of DNA.
• Every unique organism is considered a SPECIES.
• -- Organisms that look similar and can breed to
  produce fertile offspring.

14
Three Domains Of Life

• VERY BROAD CATAGORIES
• THAT CLASSIFY LIFE INTO
• SPECIFIC GROUPS.

15

• Archaea Ancient prokaryotic bacteria. No
  membrane bound nucelus.
• Bacteria Unicellular, prokaryotic organisms. No
  membrane bound nucelus.
• Eukaryotic Organisms whose cells have a membrane
  bound nucleus. Can be unicellular or
  multi-cellular.
• Protists
• Fungi
• Plants
• Animals

16
Unifying Themes of Biology
17

• Concepts that mesh all the different factions of
  biological science into a cohesive unit.
• The common themes that pertain to all life.
• Patterns that connect all organisms.

18
Biological Systems

• Biological units work as a coordinated entity,
  whether on a global or microscopic scale.
• Various parts of systems cooperate together to
  make a working unified whole.
• Example You are a collection of organ systems
  that make one working body!

19
Cell Structure

• All organisms are made up of at least one cell.
• One-celled organisms are unicellular.
• Cells have undergone specialization to develop
  multi-cellular organismslike you!

20
Form and Function

• Form and structure determines function.
• Organisms are designed with specific working
  structures that help them survive and adapt to
  their personal environment.

21
Reproduction

• All living organisms have the ability to make
  duplicates of themselves.
• Sexual Reproduction requires 2 parents.
• Asexual Reproduction requires 1 parent.

22
Heredity

• Living organisms possess DNA a molecule that
  houses genetic blueprints that pass on
  characteristics from parent to offspring.

23
Interdependence of Organisms

• Organisms are dependent upon each other to
  survive.
• Ecology The interactions of organisms between
  each other and their environment.
• Ecosystem A group of organisms that form an
  interdependent environmental community.

24
Matter, Energy and Organization

• Living organisms require a constant supply of
  energy in order to maintain body systems.
• Cellular systems are complex and highly
  organized in order to break down or build up raw
  materials to supply energy to maintain life.

25
Energy and Life

• Energy flow is systematic through ecosystems and
  organisms.
• Sun is the ultimate source of energy.
• Producers Photosynthetic organisms like plants
  that can make their own food.
• Consumers Organisms that ingest other organisms
  to obtain metabolic fuel.

26

• Organisms called autotrophs create their own
  food through the process of photosynthesis.
• Organisms call heterotrophs ingest other
  organisms and obtain nutrients through a process
  called cellular respiration.

27
Stability and Homeostasis

• The ability to maintain stable internal
  conditions within a cell. (Regulation)
• Includes temperature, pH, acid/base levels, food
  levels, and water content.
• Different organisms have different types of
  controls to maintain homeostasis.

28
Evolution

• Organisms change over time.
• Natural selection The survival of the fittest.
  
• Organisms with the strongest traits and ability
  to adapt to an environment live to reproduce.

29
Biology and Society

• The ways in which biological science directly
  effects our lives.
• Medical research
• Agriculture
• Environmental Issues
• Cloning

30
Scientific Inquiry

• Biology involves asking questions about nature.
• The natural human condition is to search for
  answers that explain natural phenomena.
