|
Information Transfer |
Information must be transmitted with cells, among cells, among organisms from one generation to the next. |
|
|
Energy Transfer |
Life required continuos input from the sun. |
|
|
Evolution |
Change in life overtime |
|
|
Cell theory |
Fundamental unifying concept of biology (cells are the basic unit structure of every living thing) |
|
|
Simple |
These organisms are unicellular |
|
|
Complex
|
The organisms are multicellular |
|
|
Prokaryotic Cells: |
No nucleus or other membrane enclosed organelles. Exclusive to bacteria and Archea |
|
|
Eukaryotic Cells |
Organelles enclosed by membranes includes nucleus, which houses DNA |
|
|
Biological Growth |
Increase in size of individual cells & number of cells, or both. |
|
|
Development |
Includes all changes during an organisms life |
|
|
Example of Development |
A human develops from a fertilized egg. |
|
|
Metabolism |
Includes all chemical activities that take place in an organism. (Nutrition, growth, repair, conservation of energy) |
|
|
Homeostatic Mechanisms (homeostatis) |
Carefully regulate metabolic precesses to maintain an appropriate, balanced internal environment. |
|
|
Examples of Homeostasis |
Temperature, bloodsugar (glucose) |
|
|
Asexual Reproduction |
Offspring have same genes as single parents |
|
|
Asexual Reproduction |
Variation occurs ONLY by mutations in Asexaul reproduction or Sexual reproduction? |
|
|
Adaptions |
Inherited characteristics that enhance an organisms ability to survive in a particular environment. (Helps to meet their needs) |
|
|
Physical, Behavioral, & Chemical |
What are the 3 types of adaptions |
|
|
Physical Adaption |
Zebras having stripes as an optical illusion for predators is what kind of adaption? |
|
|
Behavioral Adaption |
Zebras grouping together is what kind of adaption? |
|
|
Chemical Adaption |
Zebras eating grass is what type of adaption? |
|
|
- Cellular structure - Response to stimuli - Growth & Development - Self- regulated metabolism - Reproduction - Evolution |
The 6 characteristics of life include: |
|
|
DNA |
The information transfer in the cell. |
|
|
Genes |
Control Development and function of energy organisms. |
|
|
Proteins |
Large molecules. Important in determining the structure & function in cells & tissues. |
|
|
Hormones |
Animals nervous systems transmit info by electrical impulses & chemical compounds (neurotransmitters) |
|
|
- DNA transfer of info from one generation to the next - Chemical & electrical signals within & among the cells every organism -Chemical, visual displays, & sounds that allow organisms to communicate w/ one another & to interact w/ their environment. |
The information transfer includes |
|
|
Autotrophs |
Produce their own food from simple raw materials. |
|
|
Heterotrophs |
Animals that obtain energy by breaking down food molecules produced in photosynthesis. |
|
|
Primary Consumers |
Eat producers. (Horses & Cows eat grass) |
|
|
Secondary Consumers |
Eat primary consumers. (People, lions, dogs) |
|
|
Cellular Respiration |
Chemical bonds are broken in the process and stored energy is made available. |
|
|
Decomposers |
Bacteria & Fungi. Heterotrophs that obtain nutrients by breaking down non living organic material. |
|
|
Species |
Group of organisms with similar structure, function, & behavior capable of interbreeding & producing fertile offspring. |
|
|
Bacteria, Archaea, Eukarya |
3 domains |
|
|
Natural Selection |
An important evolutionary mechanism. |
|
|
Charles Darwin & Alfred Wallace |
These 2 scientist proposed a theory of evolution & suggested a mechanism: natural selection. |
