2. A cartwheel 9 + 0 structure of microtubular organisation
3. Internal structure of an eukaryotic flagella
4. Internal structure of a centrosome
Which of the following statement are correct:-
| 1. | Lysosome contain a hydrolytic enzyme which acts in pH= 5 |
| 2. | Glycosylation complete in the Golgi body. |
| 3. | Mitochondria are stained with vital stain Janus green B. |
| 4. | All of the above. |
Chloroplast differs from mitochondria in
| 1. | Having circular DNA and 70S ribosomes |
| 2. | Phase of division or duplication during cell cycle |
| 3. | Having porins in outer membrane |
| 4. | Having enzymes for carbohydrate synthesis in stroma |
Which cell organelle principally performs the function of packaging materials, to be delivered either to the intra-cellular targets or secreted outside the cell?
| 1. | Rough endoplasmic reticulum |
| 2. | Golgi apparatus |
| 3. | Smooth endoplasmic reticulum |
| 4. | Lysosomes |
Which one is incorrect
| 1. | Mycoplasmas are greater than bacteria |
| 2. | largest isolated cell is ostrich egg |
| 3. | Nerve cells are longest cells |
| 4. | The shape of the cell may vary with the function they perform |
Nerve cell is
1. largest and branched
2. longest and branched
3. longest and unbranched
4. largest and unbranched
