Statement: Many of the organelles show coordination in their functions and are considered together as an endomembrane system. Find the odd one out, from the following, with respect to this statement:
| 1. | ER | 2. | Golgi complex |
| 3. | Vacuole | 4. | Plastid |
| 1. | They do not have membranes. |
| 2. | Their functions are not coordinated with those of the ER and Golgi apparatus. |
| 3. | They lack ribosomes for protein synthesis. |
| 4. | They are exclusive to prokaryotic cells. |
Identify the structure on the basis of below given features:
| (a) | Can occupy more than 90% volume of a plant cell |
| (b) | Membrane bound space |
| (c) | Help in excretion in Amoeba |
2. Lysosome
3. Peroxisome
4. Nucleus
Why concentration of number of ions and other materials is higher in vacuole than cytoplasm?
| 1. | Vacuolar membrane is permeable for all substances |
| 2. | Tonoplast facilitates transport against concentration gradient |
| 3. | Vacuole is non-membrane structure |
| 4. | Vacuoles store and synthesize ATP to absorb ions and materials |
