1. Intro to Pre-A.P. Biology
“The Big Ideas”
*Doodle 4 Square Required!

2. Biology The Study of Life Can be divided into 4 Big Ideas: Evolution
Energy & Molecular Building Blocks
Information Storage (transmission/response)
Interdependent Relationships

3. 1. Evolution of Living Organisms
Common Descent w/Modification
Organisms that are well adapted to their environment
Ex: cacti in the desert
Natural Selection
Mutations induce variation of traits
Can either increase or decrease survival
Organizing Diversity
Taxonomy: naming organisms using rules
Scientific names use BINOMIAL NOMENCLATURE
Genus species: Homo sapien
Systematics: studying evolutionary relationships

4. 3 Domains of Life

5. Dear King Phillip Came Over For Ginger Snaps

6. 2. Energy & Molecular Building Blocks
Life Requires Nutrients and Energy
Energy= the capacity to do work
Metabolisms=chemical reactions w/in a cell
The SUN is the ultimate source of energy for life on Earth
Photosynthesis: Plants capture solar energy and convert it into chemical energy that living things can use
Living organisms maintain Homeostasis
Biological Balance
Feedback control mechanisms monitor and regulate factors
(temp., moisture, acidity, etc)

7. 3. Information Storage, Transmission, & Response
Living Organisms Reproduce and Develop
Reproduce either by fission or fertilization
Develop from immature stage to adult
Carry genetic instructions
Genes (made of Deoxyribonucleic acid) recombine during fertilization to make new and unique combinations of traits
Living Organisms Respond
Interact with environment
Can result in movement
Living Organisms have Adaptations
Modifications that can increase survivability
All living organisms have the capacity to evolve

8. 4. Interdependent Relationships
Organization of Life
From smallest to largest:
atoms, molecules, cell, tissue, organ, organ system,
organism, population, community, ecosystem,
biosphere
Increasing complexity
As you move up, each level acquires emergent properties/characteristics (and interactions between parts)
Cooperation & Competition
Can be achieved at each level
Diversity affects Interaction
Increases flexibility/adaptation

10. Characteristics of Life
Made of cells *
Reproduction *
Genetic code
Grow and develop *
Metabolize (obtain & use energy) *
Respond to environment/movement *
Maintain homeostasis (balance)
Change over time (evolve)
*Observable
