•I. Themes of Biology
•A. Cell Structure and Function
•1. Unicellular
•2. Multicellular
•3. Cell differentiation
•C. Reproduction and Inheritance - transfer of genetic material from parents to offspring.
•1. Asexual reproduction
•F. Matter, Energy, and Organization
•1. Autotroph - produces nutrients by photosynthesis.
PlantsAlgae
Cyanobacteria
•II. The World of Biology
•A. Characteristics of Life
•1. Composed of Cells - microscopic units of life.
•2. Organized at the molecular and cellular levels.......functions.
•3. Use energy in a process called metabolism......allows for growth.
•4. Homeostasis - internal balance.
•5. Growth - occurs through cell division.
•6. Reproduction - continuity of the species.
•1. Define the problem.
•2. Research.
•3. Form hypothesis - trial solution.
•4. Experiment to test hypothesis.
•Experimental group - variable tested.
•Control group - “comparison”.
Steps:
•5. Observe and record data.
•6. Draw conclusions.
•Theory - hypothesis supported by many experiments.
•Law - theory supported by many experiments.
•IV. Microscopy and Measurement
•A. Microscopes
•1. Light microscope - light produces the image.
•Magnification - enlarge.
•Resolution - clarity.
•2. Electron Microscope - uses a beam of electrons focused by magnets to produce an image.
•TEM - very powerful.
•SEM - 3-D image.
