World of Bio Notes - Unit 1
01/29
REVIEW:
***What are the 3 basic tenets of Cell Theory?***
- All living things are made up of cells
- Cells come from cells
- Cells are the basic unit of life
***What are the 7 properties of life?***
-Use energy
- Grow & Develop
- Reproduce
- Changes to the environment(stimulus)
- Evolve
- Homeostasis(maintaining)
- Order of complexity
Tissue is a group of cells working together
Tissues working together form organs
Organs working together create organ systems
Content - CHAPTER 1 PART 1
Population: all the organisms of the same species living in the same area.
Community Ecology: Multiple species living together(or in the same space)
Ecosystems: All living and nonliving things in an area
(Individual → population → community → ecosystem)
What is a biosphere?
Is the broadest level of biological organization. It includes all life on Earth, as well as all the
nonliving elements that influence it, like sunlight and water.
Levels of Organization in Biology:(KNOW FOR TEST)
- Atom
- Molecule
- Macromolecule
- Cell
- Tissues
- Organ
- Organ System
- Organism
, Makenzie Short BIO 100
- Population
- Community
- Ecosystem
- Biosphere
Phylogenetic Tree: Bacteria, Archaea, and Eukarytota
How animals are classified: We are homo sapiens(KNOW FOR TEST)
- Domain
- Kingdom(Animals)
- Phylum(Chordates)
- Class(Mammals)
- Order(Primates)
- Family(Hominids)
- Genus(Homo)
- Species(Homo Sapiens)
Sapiens(human) → Troglodytes(chimpanzee)→ Musculus(blue whale) → Naja(snake)
Human genuses and chimp’s genuses are different even though we are 98% biochemically
similar.
Branches of Biology: The study of life
- Botany(study of plants)
- Zoology(study of animals)
- Microbiology(study of microorganisms)
Key Terms:(STUDY FOR TEST)
Know definitions for: Atom, Molecule, macromolecule, organelle, cell, tissue, organ, organ
system, organism, population, community, ecosystem, biosphere
Be able to differentiate: eukaryotic vc. Prokaryote
Define terms like: biology, stimulus. And homeostasis
CHAPTER 1 PART 2
Biology: study of life
Science: is essentially knowledge of the natural world(STUDY FOR TEST)
Science is a very specific way of learning. Does not address moral questions, aesthetic questions,
or spiritual questions. Science can not investigate phenomena that can not be observed and
measured.
