Biology
The scientific study of life
1
Science
Knowledge acquired in a systematic fashion
2
Life
The condition that distinguishes organisms from inorganic objects and dead organisms.
3
Characteristics of All Living Things
Order
Homeostasis
Growth & Development
Energy Utilization
Response to the Environment
Reproduction
Evolution
4
Order
Complex but ordered organization
5
Homeostasis
Ability to maintain internal environment despite changes in the external environment
6
Growth and Development
An increase in size and often number of cells, coming as part of all of the changes that occur from the time the egg is fertilized until death.
7
Energy Utilization
Obtain and transform energy to carry out life functions.
8
Response to the environment (stimuli)
Functional activity triggered by external input.
9
Reproduction
The ability to produce offspring of their own kind.
10
Evolution
Change of populations over time.
11
General Organizations of Life - Order
Size
Diversity
12
Size levels of life
Biosphere - Ecosystem - Community - Population - Organism - Organ System - Organ - Tissue - Cells - Molecule - Atom
13
Biosphere
Regions of the Earth's crust, waters, and atmosphere inhabited by living things.
14
Ecosystem
A community plus the physical environment.
15
Community
Interacting populations in a particular area
16
Population
Organisms of the same species in a particular area
17
Organism
An individual; complex individuals contain organ systems
18
Organ System
Composed of several organs working together
19
Organ
Composed of tissues functioning together for a specific task
20
Cell
The structural and functional unit of all living things
21
Molecule
Union of two or more atoms of the same or different elements
22
Atom
Smallest unit of an element composed of electrons, protons, and neutrons
23
Taxonomy
branch of biology that names and classifies species (based on similarities and differences, generally)
24
Three Domains
Bacteria
Archaea
Eukarya
25
Bacteria
Prokaryotic - lacking membrane enclosed nucleus and organelles
26
Archaea
Prokaryotic - lacking membrane enclosed nucleus and organelles
27
Eukarya
Eukaryotic - characterized by membrane-enclosed nucleus and organelles.
28
Taxonomy system of naming
Domain - Kingdom - Phylum - Class - Order - Family - Genus - Species
