Biology Chapter 1 Exam Study Guide | Introduction
to Biology & Cell Theory
Biology
The study of living organisms
Unicellular organism
An organism made up of only one cell
Multicellular organism
An organism made up of more than one cell
Cytoplasm
Contents that fill a cell, including the cytosol and organelles
Plasma membrane
Structure that surrounds a cell and defines its boundaries
DNA
Genetic (hereditary) material of cells
Prokaryote
Cell that does not contain a nucleus
Eukaryote
Cell that a contains a nucleus
Theory
Well-substantiated explanation of all the known facts in a field of study
Cell Theory
All organisms are made of cells, cells are the basic unit of life, cells come from pre-existing cells
Theory of Evolution by Natural Selection
More individuals are produced than can survive, those who are most fit will survive and pass
their traits on
Artificial selection
