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
