Presentation Transcript

  1. Introduction to Biology

  2. What is Biology? The study of living things and their interactions with each other and their environment.

  3. “Stand By Me” Biology doesn’t stand alone Astronomy Geology Meteorology Physics Chemistry

  4. Main Topics of Study Ecology Biochemistry Cells DNA Genetics Evolution Diversity of Life Human Systems

  5. How does Biology affect you? How the human body works Humans and the environment Medical Science

  6. Several themes run through the topics of Biology Energy  the ability to do work and carry out life processes

  7. Organization Cells make Tissues make Organs Organisms make

  8. Systems and Interactions Systems interact to perform complex functions

  9. Homeostasis Maintain a consistent internal environment

  10. Evolution Change in a species over time

  11. Unity within Diversity A variety of organisms live together to form a stable environment

  12. Characteristics of Living Things All living things have 7 traits in common

  13. Made up of Cells Unicellular or multicellular

  14. Need Energy For cellular respiration (eat) or photosynthesis (make own energy from the sun)

  15. Homeostasis Maintain their internal environment

  16. Adapt and Respond Adapt – population changes to fit the environment Respond – organism reacts to what’s currently happening in the environment

  17. Grow and Develop Develop – mature/become more complex (zygote to baby) Grow – get bigger (baby to adult)

  18. Reproduce Asexually Sexually

  19. Have DNA or RNA Universal genetic code
