1. (Life's order organization) Atom
fundamental building block of all matter
2. (Life's order organization) Molecule
an association of two or more atoms
3. (Life's order organization) Cell
smallest unit of life
4. (Life's order organization) Tissue
in multicelled organisms, specialized cells organized in a pattern that allows them to perform a collective function
5. (Life's order organization) Organ
in multicelled organisms, a grouping of tissues engaged in a collective task
6. (Life's order organization) Organ system
set of organs enagaged in a collective task that keeps the body functioning properly.
7. (Life's order organization) Multicelled organism
is an individual that consists of one or more cells
8. (Life's order organization) Population
group of individuals of the same species that live in a given area
9. (Life's order organization) Community
all populations of all species in a given area
10. (Life's order organization) Ecosystem
a community interacting with its environment
11. (Life's order organization) Biosphere
all regions of Earth where organisms live
(Energy and nutrients) Energy
capacity to do work
(Energy and nutrients) Nutrient
substance that an organism needs for growth and survival but cannot make for itself
(Energy and nutrients) Producers
organism that makes its own food using energy and simple raw materials from the environment
(Energy and nutrients) Photosynthesis
process by which producers use light energy to make sugars from carbon dioxide and water.
(Energy and nutrients) Consumers
organism that gets energy and nutrients by feeding on tissues, wastes, or remains of other organisms
- animals are decomposers and consumers.
Homeostasis
set of processes by which an organism keeps its internal conditions within tolerable ranges
DNA ( Deoxyribonucleic acid)
carries hereditary information that guides growth and development
Reproduction
processes by which parents produce offspring
Inheritance
transmission from parents to offspring
(Living things differ) Biodiversity
variation among living organism
(Living things differ) Nucleus
double-membraned sac that encloses a cell's DNA
(Living things differ) Bacteria
member of a large group of single-celled organism
-DNA is not contained in its nucleus
(Living things differ) Archeans
member of a large group of single-celled organisms that differ from bacteria
-are more like Eukaryotes
(Living things differ) Eukaryotes
organisms whose cells characteristically have a nucleus
-larger and more complex than bacteria and archaens
(Living things differ) Protists
member of a diverse group of simple eukaryotes
-range from single celled to multi celled organisms
(Living things differ) Fungi
type of eukaryotic consumer that obtains nutrients by digestion and absorption outside the body
-many are decomposers
(Living things differ) Plants
multicelled typicall photosynthetic producer
-live on land or in freshwater environments
(Living things differ) Animals
multicelled consumer that develops through a series of stages and moves about during part or all of its life cycle
(Naming species) taxonomy
science of naming and classifying species
(Living things differ) Genus
a group of species that share a unique set of traits; also the first part of species name.
(Living things differ) Specific epithet
second part of a species name
(Living things differ) Taxon
Linnaean category, grouping of organisms
(Experimenting) INductive reasoning
drawing conclusion based on observation
(Experimenting) Deductive reasoning
using general idea to make a conclusion about a specific case.
-using a hypothesis
(Experimenting) Independent variable
variable controlled by an experiment in order to explore its relationship to a dependent variable
-variable being tested
(Experimenting) Dependent variable
variable that is presumably affected by the independent variabe being tested
(Experimenting) Control group
group of individuals who are not exposed to the independent variable that is being tested
