LESSON OBJECTIVE:
Review the scope of science and biology
Definitions
Science
Major Branches of Science
Social Science
Mathematics and Logic
Natural Science (hard science)
Natural Science
What would you expect to see in the museum of
natural science?
Branches of Natural Science
Physical Science
Biological Science
*interdisciplinary ( build on both life and
physical sciences
Branches of Subdisciplines of Biology
Cytology/Cell Biology
Histology
Embryology/Developmental Biology
Name/Give the other fields of Biology
Two Types of Science
Basic Science/Pure Science
-seeking knowledge,
-goal is knowledge for knowledge sake
Applied Science, or “technology”
-use science to solve real-world problems
Give examples on how basic science and applied
science work together.
Attributes of Life
What do you mean when you say something is
alive?
All organisms have the same biological
characteristics.
Attributes of Life
1. Growth - increase in size (assimilation of
nutrients)
*one-celled organism vs multicellular organism
* plants vs animals
* controlled by the chemical substance produced
by the organisms
*LT vs NLT
intussusception
accretion
Attributes of Life
2. Reproduction
Asexual reproduction
Sexual reproduction
3. Metabolism
catabolism
anabolism
Attributes of Life
4. Homeostatic Response/Homeostasis
Irritability
Adaptability/adaptation
5. Nutrition
nutrients for ?
Attributes of Life
6. Mutation
somatic mutation
germ mutation
7. Biological Organization
*single-celled organisms are remarkably complex
cell (atoms- molecules- cell organelles, cell
inclusions)
Attributes of Life
7. Biological Organization
* multicellular organisms
cells-tissues-organs-organ systems-organims
8. Movement
*animals- motile
*plants-stationary; bases on their responses to
stimuli
Attributes of Life
9. Life span
with specific life span
controlled by genetic composition (rate of aging)
external environment (accident, diseases, etc.)
10. Form and Shape
controlled by genetic composition
environmental factors
Critical Thinking Questions
Answer the questions briefly (5 points each)
1. Consider the levels of organization of the biological world,
and place each of these items from smallest level of
organization to most encompassing: skin cell, elephant, water
molecules, planet Earth, tropical rainforest, hydrogen atom,
wolf pack, liver.
2. Select two items that biologists agree are necessary in order
to consider an organism “alive”. For each, give an example of a
non-living object that otherwise fits the definition alive.
