The correct chronological sequence [beginning from the earliest] with respect to fungal sexual cycle will be:
1. Karyogamy, Plasmogamy and Meiosis
2. Meiosis, Plasmogamy and Karyogamy
3. Plasmogamy, Karyogamy and Meiosis
4. Meiosis, Karyogamy and Plasmogamy
| 1. | is a resting spore | 
| 2. | is involved in nitrogen fixation | 
| 3. | is gas vacuole | 
| 4. | is where carbon dioxide concentration mechanism is applied | 
| Statement I: | Association between mycobiont and phycobiont is found in Lichens. | 
| Statement II: | An association between roots of higher plants and fungi is called mycorrhiza. | 
| I: | Eukaryotic cell type | 
| II: | Absent cell wall | 
| III: | Capability to act as a heterotroph when deprived of sunlight | 
| 1. | Kingdom Monera, as a mycoplasma | 
| 2. | Kingdom Protista, as a euglenoid | 
| 3. | Kingdom Protista, as a dinoflagellate | 
| 4. | Kingdom Animalia, as a sponge | 
| Assertion (A): | The two kingdom classification used for a long time was found inadequate |

| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). | 
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). | 
| 3. | (A) is true but (R) is false. | 
| 4. | Both (A) and (R) are false. | 
| Assertion (A): | The cell walls of diatoms are indestructible | 
| Reason (R): | In diatoms, cell walls are embedded with silica | 
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). | 
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). | 
| 3. | (A) is true but (R) is false. | 
| 4. | Both (A) and (R) are false. | 
| Assertion (A): | Diatoms leave behind large amount of cell wall deposits in their habitat, which gets accumulated over billions of years | 
| Reason (R): | -Silicious cell walls in diatoms are indestructible | 
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). | 
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |

| Assertion (A): | Infectious agent discovered by T.O. Diener, lack protein coat that is found in viruses | 
| Reason (R): | Viroids have RNA of low molecular weight | 
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). | 
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
