Eukaryotic Vs. Prokaryotic Cells Flashcards
1
Q
what is a prokaryotic cell
A
small and simple (single celled organism) cells, thought to be the first on earth, without a definitive uncles
2
Q
types of prokaryotes
A
- bacteria
- archea
3
Q
parts of bacteria
A
- pili
- free DNA (nucleoid region)
- capsule
- cell wall (made out of peptidoglycen)
- flagellum
- plasmid DNA
- cell membrane + cytoplasm
4
Q
how do bacteria reproduce
A
binary fission (asexual reproduction)
5
Q
size of the ribosomes of prokaryotic cells
A
70s
6
Q
what is a eukaryotic cell
A
a cell with membrane-bound organelles; they make up the animal, plant, fungi, algae, protozoa etc organisms
7
Q
why are the organelles within the eukaryotic cell membrane bound
A
-to allow for specific function and chemical reactions to be separated and to increase efficiency (COMPARTMENTALIZATION)
8
Q
two common types of eurkaryotes
A
-plant and animal
9
Q
compare prokaryotic and eukaryotic cells
A
PROKARYOTES
- dna in a ring form without protein
- DNA free in the cytoplasm
- no mitochondira
- 70s ribosomes
- no membrane bound organelles
- size less than 10um
EURKAYOTES
- Dna with proteins as chromosomes
- dan enclosed with a nuclear envelope
- mitochondria present
- 90s ribosomes
- membrane bound organelles
- size more than 10um
