2
Q
list features of a eukaryotic cell
A
- 100μm in diameter
- Linear DNA associated with histone proteins to form chromosomes
- cell division through mitosis or meiosis
- 80S ribosomes
- many types of organelles that are membrane bound
- cell wall present in plants (made of cellulose or lignin or in fungi made of chitin)
3
Q
list features of prokaryotic cells
A
- 0.5 -5μm in diameter
- naked circular DNA found in cytoplasm
- cell division by binary fission
- 70S ribosomes
- very few organelles- not membrane bound
- cell wall made of peptidoglycan (amino acids and polysaccharides)
4
Q
list ever-present features of prokaryotic cells
A
- cell wall
- cell surface membrane
- circular DNA
- ribosomes
- cytoplasm
5
Q
list partially-present features of prokaryotic cells
A
- capsule -protection
- flagellum- motion
- plasmid- small circle of DNA
- infolding of cell surface membrane- photosynthesis or nitrogen fixation
- pili- attachment to other cells
