Water is essential for Bryophyta:
| 1. | For fertilization and homosporous nature |
| 2. | Water should be filled in the archegonium for fertilization |
| 3. | Water is necessary for the movement of sperm |
| 4. | For the dissemination of spores |
Which of the following statement is true for bryophyta:
| 1. | Along with water absorption roots also provide anchorment to plants |
| 2. | Sporophyte is dominant |
| 3. | Gametophyte is dominant and sporophyte is mostly parasitic |
| 4. | Gametophyte is parasitic |
Moss peat is used as a packing material for sending flowers and live plants to distant places because:
1. it is easily available
2. it is hygroscopic
3. it reduces transpiration
4. it serves as a disinfectant
In a moss the sporophyte:
| 1. | is partially parasitic on the gametophyte |
| 2. | produces gametes that give rise to the gametophyte |
| 3. | arises from a spore produced from the gametophyte |
| 4. | manufactures food for itself, as well as for the gametophyte |
Male and female gametophytes are independent and free-living in:
1. Mustard
2. Castor
3. Pinus
4. Sphagnum
A plant shows thallus level of organisation. It shows rhizoids and is haploid. It needs water to complete its life cycle because the male gametes are motile. Identify the group to which it belongs to

4. bryophytes
| List-I | List-II | ||
| A. | Microscopic angiosperm | I. | Salvinia |

| C. | Thalloid bryophyte | III. | Sequoia |
| D. | Heterosporous pteridophyte | IV. | Wolffia |
1. A-I, B-III, C-II, D-IV
2. A-IV, B-III, C-II, D-I
