Chapter 1 - Biology, The Study of Life Flashcards
Biology
The scientific study of life
Organ
Combination of two or more different tissues performing a common function
Species
Group of similarly constructed organisms capable of interbreeding and producing fertile offspring; organisms that share a common gene pool; the taxon at the lowest level of classification
Ecosystem
Biological community together with the associated abiotic environment; characterized by energy flow and chemical cycling
Tissue
Group of similar cells that preform a common function
Domain
The primary taxonomic group above the kingdom level; all living organisms may be placed in one of three domains
Community
Assemblage of populations interaction with one another with in the same enviroment
Cell
Smallest unit that displays the properties of life; always contains cytoplasm surrounded by a plasma membrane
Kingdom
One of the categories used to classify organisms; the category above phylum
Population
Organisms of the same species occupying a certain area
Molecule
Union of two or more atoms of the same element; also, the smallest part of a compound that retains the properties of the compound
Prokaryote (Prokaryotic Cell)
Organism that lacks the membrane-bounded nucleus and membranous organelles typical of eukaryotes
Organism
Individual living thing
Hypothesis
Supposition that is formulated after making an observation; it can be tested by obtaining more data, often by experimentation
Eukaryote (Eukaryotic Cell)
Type of cell that has a membrane-bounded nucleus and membranous organelles
