prokaryotic cell structure Flashcards
1
Q
nucleoid
A
single chromosome (loop) holds genetic information
2
Q
pili (pl. pilus)
A
fingerlike projections used to secure/anchor bacterium on a different surface
some specialized pili can form a “cytoplasmic bridge” for conjunction
3
Q
ribosomes (polyribosomes)
A
synthesize protein
4
Q
flagellum (pl. flagella)
A
used for locomotion
5
Q
plasmid
A
small loop of DNA containing only a few genes
6
Q
cytoplasm
A
the material inside the cell
7
Q
cell membrane
A
controls flow of materials in/out of the cell
8
Q
cell wall
A
(2 types) for additional protection
9
Q
capsule
A
a slimy covering on top of the cell wall for additional protection
10
Q
what structure do only some bacterial cells have?
A
capsule
