Introduction to Cells
Cells - are the basic units of life that compose all living things. They are more different
structurally and functionally than they are similar and are very similar chemically
o Viruses are not considered living things because they need a host in order to
reproduce (cannot reproduce on their own)
o Characteristics Shared by All Cells (9):
Composed of 4 major macromolecules
Genetic material is carried and stored n the form of DNA
DNA is transcribed into RNA and RNA is translated into proteins (Central
Dogma)
Appearance, behavior, and function is dictated by proteins
Reproduce on their own
Respond to stimuli
Adapt to their environment
Are highly organized
Maintain a constant internal environment
Learning Objective #1 - Differentiate between eukaryotic and prokaryotic cells.
Prokaryotes (Bacteria)
Eukaryotes (Protists, Fungi, Plants,
Animals)
Organelles
Little to none; do not have a
nucleus
Many; has a nucleus
DNA
Circular
Linear; found in nucleus
RNA and Protein
RNA and proteins synthesized in
the same place
RNA synthesized in the nucleus
and proteins in the cytosol
Organization
Unicellular
Unicellular or multicellular
Cell Division
Binary fission
Mitosis and meiosis
Size
Smaller in size
Larger in size

Learning Objective #2 - Identify the various components of a eukaryotic cell and describe the
function of each organelle in a eukaryotic cell.
Microtubule tubular polymers of tubulin that form part of the cytoskeleton and can
provide shape and structure to the cytoplasm of the cell
Nuclear Envelope a membrane that separates the nucleus from the cytoplasm in eukaryotic
cells
Endoplasmic Reticulum site where most cell components and exports are made (i. e.
protein synthesis)
Mitochondria generates usable energy from food to power the cell’s activities
Lysosome deals with intracellular digestion, nutrient release, molecule breakdown, and
recycling of macromolecules
Plasma Membrane forms the external boundary of the cytoplasm of a cell and regulates
the passage of molecules in and out of the cytoplasm
Golgi Apparatus modifies and packages molecules made in the ER to secrete or transport
to another cell
Peroxisome provides a safe environment for biochemical reactions that release toxic
products
Endosome Series of compartments that sorts and recycles endocytosed materials to the
plasma membrane
