1. In Gram negative bacteria, cell wall is sorrounded by a polysaccharide layer which is numbered as '1' in the diagram
cell membrane
cell wall
capsule
outer membrane
2. In the figure label '2' is made up of peptidoglycan. It is the
bacterial cell wall
bacterial cell membrane
bacterial capsule
bacterial inner membrane
3. The structure labeled 5 is formed as invagination of bacterial cell membrane into the the cytoplasm. This structure is involved in bacterial DNA replication and is the
plasmid
cytosol
ribosome
mesosome
4. The structure labelled '6' helps in cell to cell attachment during bacterial conjugation. It is
pili
cilia
flagella
spinae
5. Identify the structure numbered '9' which is involved in protein synthesis
mesosome
peroxisome
ribosome
episome
6. It is a selectively permeable layer made up of lipoproteins which is numbered 3 is
cell wall
peptidogylcan layer
cell membrane
polysaccharide layer
7. The structure labelled 10 are organs of locomotion in motile bacteria. It is
flagella
cilia
pili
psuedopodia
8. In bacteria, DNA is not sorrounded by a membrane. The region where DNA is located is labeled 7 and is called as
nucleus
pronucleus
nucleoid
all of these
9. This is the region where all major cellular reactions takes place. The region numbered '4' is called
mesosome
protoplasm
cytoplasm
cytosol
10. The structure labeled '8' is the extra-chromosomal, double stranded, circular DNA present in bacterial cell. It is called as
cosmid
plasmid
phagemid
extra-nuclear DNA
