|
Bacteria |
Are the most diverse and widespread prokaryotic and are now classified into multiple kingdoms |
|
|
Archaea |
Any group of single celled prokaryotic organisms(organisms whose cell lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria |
|
|
Biosphere |
All life on Earth and all places where life exists |
|
|
Ecosystem |
All living things in a particular area. Along with all non-living components of the environment with which life interacts such as soul, water,atmospheric gases, and light. |
|
|
Community |
The array of organisms inhabiting a particular ecosystem. (e.g. the community in our meadow ecosystem includes many kinds of plants, various animals, mushrooms and fungi, and enormous numbers of diverse microorganisms, such as bacteria that are too small to see without a microscope.) a community is therefore a set of populations that inhabit a particular area
|
|
|
Population |
Consists of all the individuals of a species living within the bound of an area. (E.g a meadow includes a population mule deer) |
|
|
Organisms |
Individual living things |
|
|
What are the levels of biological Organization? |
1.) the biosphere 2.) ecosystems 3.) communities 4.) Populations 5.) Organisms 6.) Organs 7.) Tissues 8.)Cells 9.) Organells 10.) Molecules |
|
|
Reductionism |
Zooming in through the levels of the biological hierarchy at ever-finer resolution. This method reduces complex systems to simpler components. |
|
|
organ |
A body part that is made up of multiple tissues and has specific functions in the body. Leaves, stems, and roots are the major organs of plants. Within an organ, each tissue has a distinct arrangement and contributes particular properties to organ function. |
|
|
Tissue |
tissue is a group of cells that work together, performing a specialized function. |
|
|
Cell |
The cell is life’s fundamental unit of structure and function. |
|
|
-organelles |
organelles, the various functional components present in cells. Organelles are only found in eukaryotic cells and are absent in cells from prokaryotes such as bacteria. (e.g. mitochondria, golgi apperatus, chloroplasts) |
|
|
Molecule |
A molecule is a chemical structure consisting of two or more units called atoms, |
|
|
Cell Theory |
first developed in the 1800s,states that all living organisms are made of cells, which are the basic unit of life. |
|
|
eukaryotic cell |
A eukaryotic cell contains membrane-enclosed organelles. All other forms of life, including plants, fungi,protists, and animals, are composed of eukaryotic cells. unicellular or multi-cellular. consists on DNA, Ribosomes |
|
|
prokaryotic cells |
Bacteria and archaea, single-celled, Consists of DNA, ribosomes, |
