Levels of Organization
-a group of organs that work together to perform a certain task
Organ system
-An organism consisting of more than one cell
Multicellular
-a kingdom made up of non-green, eukaryotic organisms that reproduce by using spores, and get food by breaking down substances in their surroundings
Kingdom Fungi
-an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are also called producers.
Autotrophs
-may or may not contain a cell wall; reproduce sexually or asexually; can be unicellular or multicellular; organisms have an organized and complex cellular structure with genetic material being contained in a well-defined nucleus.
Domain Eukarya
-a group of tissues that perform a specific function or group of functions
Organ
-An evolutionary tree (branching diagram) that diagrams the ancestral relationships among organisms.
Cladogram
-a kingdom made up of complex, multicellular organisms that lack a cell wall, can usually move around , and quickly respond to their environment.
Kingdom Animalia
-type of cell that contain no nucleus; all genetic information is located in the cytoplasm
Prokaryotic cell
-represents the largest differences among organisms; most inclusive level of classification
Domain
-the basic structural and functional unit of all organisms
Cell
-method for identifying and classifying objects using questions to repeatedly divide organisms into two categories
Dichotomous keys
-a kingdom of mostly one-celled eukaryotic organisms that are different from plants, animals and fungi
Kingdom Protista
-an animal that can't make its own food, so they have to eat other things, like plants or other animals, to survive; Includes all animals and fungi; also called consumers.
Heterotrophs
-single-celled organisms (prokaryotes-lack cell nucleus); have the ability to survive extreme conditions; can be found in a variety of environments, even outer space!
Domain Archaea
-a group or layer of cells that are alike and that work together to perform a specific function
Tissue
-a Swedish physician and botanist; classified organisms based on similar structures; He also was responsible for giving each kind of living thing a 2-part Scientific name.
Carolus Linnaeus
-the second highest taxonomic rank, just below domain
Kingdom
-type of cell that contain a nucleus and other membrane-bound organelles; includes the cells of plants and animals
Eukaryotic cell
-a group of organisms that are closely related and can mate to produce fertile offspring
Species
-an individual form of life that is capable of growing, taking in nutrients, and usually reproducing (organ systems working together)
Organism
-the branch of science that formally names and classifies organisms by their structure, function and relationships
Taxonomy
-a kingdom made up of complex, multicellular organisms that are usually green, have cell walls made of cellulose, cannot move around, and use the sun's energy to make sugar by photosynthesis
Kingdom Plantae
-An organism consisting of ONLY one cell
Unicellular
-prokaryotes (single-celled organisms that lack a nucleus); usually have a cell wall & reproduce by cell division; they can live in almost any environment - soil, water, and even in the human body!
