Q. No.The endomembrane system of the cell includes
1. ER + Golgi body + Mitochondria
2. ER + Golgi body + Vacuole + Microtubules
3. ER + Golgi body + Lysosome + Vacuole
4. ER + Golgi body + Chloroplast + Lysosome
ER, Golgi complex, lysosomes and vacuoles are included in endomembrane system because :-
1. Their function are similar
2. Their structure are same
3. Their function are co-ordinated
4. Golgi complex, lysosomes and vacuoles are originated from the ER
Which of the following statement is incorrect with respect to endomembranous system?
| 1. | Found only in eukaryotes. |
| 2. | The organelle of this system function in coordinated manner. |
| 3. | It includes endoplasmic reticulum, golgi complex, lysosome and vacuole. |
| 4. | Found in that cell in which cyclosis is absent |
Which of the following organelles is not correctly matched with its feature?
| Organelle | Feature | |
| 1. | Smooth endoplasmic reticulum | Synthesis of steroidal hormones in animals |
| 2. | Golgi apparatus | Formation of glycoproteins and glycolipids |
| 3. | Lysosomes | Rich in alkaline hydrolases |
| 4. | Elaioplasts | Store oils and fats |
In the given diagram, what is true for both A and B?
1. They are involved in protein synthesis
2. They synthesize steroidal hormones in animal cells
3. They are a part of endomembranous system of a eukaryotic cell
4. They are continuous with the inner membrane of the nucleus
Select the incorrect statement(s) with respect to functions of various cellular components
| a. | Middle lamella works as glue to hold the adjacent cells together. |
| b. | Mitochondria, chloroplast and vacuoles are part of the endomembrane system as their functions are coordinated. |
| c. | Lipoidal steroid hormones are synthesized by ER component which is not associated to 80 S ribosomes. |
1. Only b
2. Only a
3. Both a and c
4. Both b and c
Which of the following statement is true for a secretory cell?
| 1. | Golgi apparatus is absent |
| 2. | Rough Endoplasmic Reticulum (RER) is easily observed in the cell. |
| 3. | Only Smooth Endoplasmic Reticulum (SER) is present. |
| 4. | Secretory granules are formed in nucleus. |
Consider the following statements:
| I: | In animal cells, lipid like steroidal hormones are synthesized in SER. |
| II: | Golgi apparatus is the important site for formation of glycoproteins & glycolipids. |
| III: | Lysosomes carry alkaline hydrolases. |
Which of the above statements are true?
1. I and II only
2. I and III only
3. II and III only
4. I, II and III
