DNA is contained in one or more chromosomes located in a non-membrane bound nucleoid region in
|
Prokaryotes
|
|
|
DNA is contained in one or more chromosomes located in a membrane bound nucleus in
|
Eukaryotes
|
|
|
A phospholipid bilayer with proteins that separates the cell from the surrounding enviornment and functions as a selective barrier for the import and export of materials
|
Plasma Membrane
|
|
|
The rest of the material of the cell within the plasma membrane and excluding the nucleoid region or nucleus.
|
Cytoplasm.
|
|
|
Cytoplasm consists of a fluid portion called
|
Cytosol
|
|
|
The structures on which protein synthesis takes place.
|
Ribosomes
|
|
|
They lack a nucleus and membrane bound organelles
|
Prokaryotic cells
|
|
|
Cell contains large numbers of ribosomes which are used for protein synthesis
|
Prokaryotic cells
|
|
|
Where does cellular respiration occur in prokaryotic cells?
|
Plasma Membrane
|
|
|
Outside of the plasma membrane in most Prokaryotes is a fairly rigid wall of peptidoglycans that protect the cell from
|
Osmotic Lysis
|
|
|
Some bacteria have flagella that are used for
|
Locomotion
|
|
|
Some bacteria have pili which are used to
|
Connect two cells for genetic material
|
|
|
This provides a sticky protective layer outside the cell wall of some bacteria
|
Capsule
|
|
|
This type of cell contains a membrane bound nucleus and numerous membrane enclosed organelles (mitochondria, lysosomes, golgi apparatus)
|
Eukaryotes
|
|
|
The nucleus is bound by this
|
nuclear envelope
|
|
|
In the nuclear membrane, material enters and leaves through these
|
Nuclear Pores
|
|
|
consists of microtubules, intermediate fibers, and microfilaments.
|
Cytoskeleton
|
|
|
Maintain cell shape, anchors organelles and cause cell movement
|
Cytoskeleton
|
|
|
More permanent than microtubules or microfilaments
|
Intermediate filaments
|
|
|
This is not part of a prokaryotic cell
|
Chloroplast
|
|
|
Using the light microscope, which would allow discrimination between eukaryotes and prokaryotes?
|
Observation of nuclei.
|
|
|
A eukaryotic cell can ingest a prokaryotic cell by
|
Phagocytosis
|
|
|
The nuclear area of the bacterial cell
|
Contains the bacterial chromosome
|
|
|
Spherical shaped bacteria that divide and remain attached in chainlike patterns are called
|
Streptococci
|
|
|
Polyphosphate (volutin), carboxysomes, and magnetosomes are examples of
|
Inclusion bodies
|
|
|
Spirochetes and spirilla are both spiral shaped bacteria. However, they differ in that spirochetes have ________________ and spirilla do not
|
Endoflagella
|
|
|
Chemotaxis refers to the ability of microorganisms to
|
Move toward or away from chemical stimuli
|
|
|
Gram-negative cells contain a periplasmic space which is
|
Rich in degradative enzymes
|
|
|
The pressure required to prevent the movement of pure water into a solution containing some solutes.
|
Osmotic Pressure
|
|
|
Active transport is different from facilitated diffusion because active transport requires
|
Energy in the form of ATP
|
