What is the nucleoid region used for? - To store genetic information
in prokaryotes
True or false: If false, make it true. The nucleoid region is bound by a
membrane and does not contain bacterial chromosomes and DNA? -
False The nucleoid region is NOT bound by a membrane and DOES
contain bacterial chromosomes and DNA.
Bacterial chromosomes are in what shape? - Circle
Define plasmids - Small, circular region of DNA.
How many plasmids do bacterial cells usually have? - Dozens
Which organelle can carry small amounts of genetic info and can
replicate independently of one another? - Plasmids
The __________ is filled with __________ - intracellular region
cytoplasm
What is the responsibility of cytoplasm - Holding ribosomes and
plasmids in the cell.
Are ribosomes bound by a membrane? - No
Cells can be broken down into what two groups? - Prokaryotic and
Eukaryotic
What type of cell contains a membrane bound nucleus, and
organelles that are specific to each cell? - Eukaryotic
What is the size range for Eukaryotic cells? - 10-100 micro meters
What is the difference between animal and plant eukaryotic cells? -
Animal cells don't have a cell wall. Plants have a rigid cell wall.
Can eukaryotic cells be single or multicellular? - Both
Which type of cell is less complex? - Prokaryotic
Which type of cell lacks a nucleus and other membrane bound
organelles? - Prokaryotic
Which type of cell is smaller? - Prokaryotic
What is the size range of a prokaryotic cell? - 1-5 micrometers
Are prokaryotic cells always single celled? - Yes
What 2 kingdoms are prokaryotic organisms apart of? - Bacteria
and Archaea
What is something eukaryotic and prokaryotic cells have in
common? - Both have a plasma membrane, cytosol, and
chromosomes
What is unique about bacterial ribosomes? - Their RNA and protein
are unique. This allows for the creation of antibiotics b/c they only
target the unique RNA and protein in bacteria.
Contents of bacterial cells are enclosed in what? - Plasma
membrane
What occurs in the plasma membrane? - Diffusion of ions/molecules
and area for metabolic functions
Prokaryotic cells do not contain a __________ which is important for
__________ - mitochondria
aerobic respiration
