M1: Classification of Cells Flashcards
1
Q
prokaryotic cells overview
A
- means “before kernel”
- no nucleus, DNA found in cytoplasm
- 2 types
2
Q
types of prokaryotic cells (2)
A
- (eu)bacteria
2. archaea
3
Q
bacteria overview
A
- may appear as isolated cells or in chains or clusters
- may demonstrate motility
- ex: streptococcus, e coli, mycobacterium tuberculosis
4
Q
common shapes of bacteria (4)
A
- coccus
- bacillus
- vibrio
- spirillum
5
Q
categories of eukaryotic cells (4)
A
- animalia
- platae
- fungi
- protista
6
Q
archaea
A
- similar to bacteria but genetically distinct
- can survive in very hard conditions –> “extremophiles”
7
Q
eukaryotic cells
A
- diverse category of microorganism
- common factor = contain membrane-bound nucleus (that holds DNA)
8
Q
animalia
A
- multicellular organisms (including animals/humans)
- heterotrophic, so must consume nutrients from environment
- capable of movement (motile)
9
Q
plantae
A
- multicellular organisms
- get most of their energy thru photosynthesis
10
Q
fungi
A
- unicellular or multicellular organisms
- heterotrophic
- contain chitin (glucose derivative) in cell walls
- ex: mushrooms, yeast (unicellular)
11
Q
heterotrophic
A
cannot produce own energy
12
Q
photosynthesis
A
process of converting energy of sunlight into sugar for energy
13
Q
coccus
A
spherical bacteria
14
Q
bacillus
A
rod-shaped bacteria
15
Q
vibrio
A
curved rod-shaped bacteria
