Q. No.Prokaryotic mesosomes do not help in:
1. Cell wall formation
2. DNA replication
3. Respiration
4. Photosynthesis
A feature unique to prokaryotes would be:
1. A cell wall not made up of cellulose
2. An extrachromosomal plasmid DNA
3. A cell membrane of peptidoglycan
4. Presence of inclusions
Chromatophores are:
1. present in liopolysaccharide layer of gram negative bacteria
2. colored pigments present in fluorescent bacteria
3. vesicles that store pigments in prokaryotic cells
4. extensions on membrane in cynobacteria
Select the wrong statement.
| 1. | Bacterial cell wall is made up of peptidoglycan |
| 2. | Pili and fimbriae are mainly involved in motility of bacterial cells |
| 3. | Cyanobacteria lack flagellated cells |
| 4. | Mycoplasma is a wall-less microorganism |
Which of the following is not a feature of the plasmids?
1. Circular structure
2. Transferable
3. Single-stranded
4. Independent replication
Which is not true for prokaryotic cells ?
| 1. | They are smaller than eukaryotic cells. |
| 2. | They lack membrane-bound organelles. |
| 3. | Their genetic material is localised within nucleoid. |
| 4. | They contain a well developed cytoskeleton. |
Identify the accurate explanation of mesosome.
It is :
| 1. | a specialised structure of prokaryotic cell formed by extension of plasma membrane into the cytoplasm |
| 2. | the middle layer of the prokaryotic cell wall |
| 3. | the organelle of eukaryotic cell which helps in lipid synthesis |
| 4. | the middle layer of eukaryotic cell wall. |
