The plant body of moss (funaria) is
1. completely sporophyte
2. predominatly sporophyte with gametophyte
3. completely gametophyte
4. predominantly gametophyte with sporophyte
Secondary protonema of moss
| 1. | Helps in propagation by fragmentation. |
| 2. | Helps in propagation by budding. |
| 3. | Have leafy stage as lateral bud. |
| 4. | All the above |
In mosses, the sex organs are seen in:
1. Protonema stage
2. Leafy stage
3. Capsule of the sporophyte
4. Seta of the sporophyte
Identify the incorrect statement regarding mosses:
| 1. | Leaves are one cell thick except at the midrib and lack stomata. |
| 2. | The first gametophyte stage is protonema, that is creeping and green. |
| 3. | The second stage is the leafy stage, which develops from the secondary protonema as a lateral bud. |
| 4. | Rhizoids are elongated and unicellular. |
Leafy stage develops from the secondary protonema as a
1. Apical bud
2. Axillary bud
3. Lateral bud
4. Meristem
