SELU GENERAL BIOLOGY 106 - EXAM 2
QUESTIONS AND ANSWERS
Cell Theory - Correct Answers -all living things are made up of cells, cells are the basic
unit of life, cells arise from pre-existing cells
Structural Components of all cells - Correct Answers -all cells have cytoplasm, a plasma
membrane, and ribosome
Molecular Components of all cells - Correct Answers -all cells have proteins,
carbohydrates, lipids, and nucleic acids
Functional Components of all cells - Correct Answers -all cells have the ability to survive
and reproduce on their own
Hershey and Chase - Correct Answers -concluded that DNA, not protein, is the material
that stores hereditary information
Chargaff - Correct Answers -discovered the DNA complementary pattern [A=T and
G=C]
Watson and Crick - Correct Answers -discovered the DNA double helix
Stahal - Correct Answers -discovered the semi-conservation replication of DNA (each
DNA double helix is composed of an old strand and new strand)
DNA Replication - Correct Answers -the process of DNA making an exact copy of itself;
occurs before cellular reproduction; occurs in the nucleus of eukaryotic cells, divided up
into three phases based on the enzymes present (DNA helicase, polymerase, and
ligase
Prokaryotic Cells - Correct Answers -Bacteria and Archaea
Eucharyotic Cells - Correct Answers -fungi, protist, plants, and animals
Cell Wall - Correct Answers -external structure and support, located outside the plasma
membrane, provides the cell with protection and support
, Flagella - Correct Answers -movement, extension of plasma membrane, provides the
cell with movement, long and singular movement
Plasma Membrane - Correct Answers -thin membrane around the cell, composed of
phospholipid bilayer and proteins
Cytoplasm - Correct Answers -internal space between the plasma membrane and
genetic material
Ribosomes - Correct Answers -protein maker, small structures that make proteins
Cilia - Correct Answers -movement, short and numerous movement
Organelle - Correct Answers -A tiny cell structure that carries out a specific function
within the cell
Nucleus - Correct Answers -membrane bound location of DNA
Smooth ER - Correct Answers -make lipids and carbohydrates
Rough ER - Correct Answers -make proteins that will leave the cell
Golgi Body - Correct Answers -a structure in a cell that receives proteins and other
newly formed materials from the endoplasmic reticulum, packages them, and distributes
them to other parts of the cell.
Mitochondria - Correct Answers -makes energy (ATP) for cell
Lysome - Correct Answers -intracellular digestion
Central Vacuole - Correct Answers -storage for water and other substances
plants have one large central vacuole
Cytoskeleton - Correct Answers -internal structure and support
Cell Wall - Correct Answers -a rigid boundary surrounding cells of many prokaryotes,
protists, plants, and fungi
Chloroplast - Correct Answers -location of photosynthesis
Plant cells only have these... - Correct Answers -cell wall, central vacuole, and
chloroplasts
Plasma Membrane's three basic functions - Correct Answers -separation, selectively
permeable regulation, and communication
