organism
|
any living thing
|
|
biology
|
the study of life
|
|
organization
|
the high degree of order within an organism's internal and external parts and in its interactions with the living world
|
|
cell
|
the smallest unit that can carry out all of life's processes
|
|
unicellular
|
organisms that are made up of one cell
|
|
multicellular
|
organisms that are made up of many cells
|
|
3 requirements for a cell
|
1. covered by a membrane
2. contains all genetic info necessary for replication 3. able to carry out all cell functions |
|
organs
|
structures that carry out specialized jobs within an organ system
|
|
tissues
|
groups of cells that have similar abilities and that allow an organ to function
|
|
organelles
|
tiny structures within a cell that carry out all functions for the cell to stay alive
|
|
biological molecules
|
the chemical compounds that provide physical structure and that bring about movement, energy use, and other cellular functions
|
|
stimulus
|
a physical or chemical change in the internal or external environment
|
|
response
|
an organism's reaction caused by a stimulus to adapt to meet that organism's needs
|
|
homeostasis
|
the maintenance of a stable level of internal conditions even though environmental conditions are changing constantly
|
|
metabolism
|
the sum of all the chemical reactions that take in and transform energy and materials from the environment
|
|
development
|
the process by which an organism becomes a mature adult
|
|
gene
|
a short segment of DNA that contains instructions for a single trait of an organism
|
|
sexual reproduction
|
hereditary information combines from 2 organisms of the same species
|
|
asexual reproduction
|
hereditary information from just one organism is copied and replicated in a brand new organism, thus the original organism and the new organism are genetically the same
|
|
evolve
|
to change through time
|
|
list 8 characteristics of life

|
list in order the levels of organization from largest to smallest
|
organism--> organ system--> organ--> tissue--> cell--> organelle--> molecule--> atom

|
1.animalia
2.plantae 3.fungi 4.protista 5.archaea 6.bacteria |
|
ecology
|
the branch of biology that studies organisms interacting with each other and the environment
|
|
ecosystems
|
communities of living species and their physical environments
|
|
evolution
|
or descent with modification, the process in which the inherited characteristics within populations change over generations
|
|
natural selection
|
organisms that have certain favorable traits are better able to survive and reproduce successfully than organisms who lack these traits
|
|
adaptation
|
traits that improve an individual's ability to survive and reproduce
|
