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
How can a bacteria go through aerobic respiration without a
mitochondria? - The bacteria's plasma membrane will fold to create
a space for the chemical reactions in aerobic respiration
Zeker de moeite als je een groot vak op het nippertje niet helemaal rond zou krijgen.
Soms koop ik meerdere samenvattingen over 1 boek. Dit helpt mij als ik onvoldoende tijd heb om het hele boek te lezen en zelf geen samenvatting kan maken.
Downloaden maar! Goede site met goede documenten. De prijs wordt aangepast o.b.v. de beoordelingen.
Nadat ik Knoowy ontdekt heb, ga ik regelmatig op zoek naar eventuele bruikbare samenvattingen! Heel erg handig!
Goed voor als je een samenvatting nodig hebt of de leerstof niet zo goed snapt, maar ook voor als je bijles nodig hebt.
Knoowy is zeker aan te raden. Het is goedkoper dan andere platforms.
Prima samenvattingen van veel verschillende vakken die je goed kunt gebruiken.
Een handige site voor het aankopen van samenvattingen voor examens.
