What is the function of the gemmae produced by some liverworts?
1. a water gathering structure
2. a light gathering structure
3. a sexual structure
4. an asexual structure
The life cycle of Ectocarpus, Polysiphonia and kelps is:
1.Diplontic
2.Haplontic
3.Aplantic
4.Haplo-diplontic
Evolutionarily, the first terrestrial plants to possess vascular tissues are:
| 1. | Bryophytes | 2. | Pteridophytes |
| 3. | Gnetales | 4. | Cycads |
All the following are characteristics of bryophytes except:
| 1. | spore producing |
| 2. | dominant gametophyte |
| 3. | lignified tissues |
| 4. | producing antheridium and archegonium |
Which of the following Greek root word means "naked" and hence gives name to plants like cycas and pines?
| 1. | angeion | 2. | sperm |
| 3. | gymnos | 4. | gynos |
The term ‘strobilus’ in a gymnosperm defines a:
| 1. | collection of megasporophylls |
| 2. | collection of microsporophylls |
| 3. | site of sporangial development |
| 4. | collection of megasporophylls, microsporophylls and/or a site of sporangial development |
Female sex organs of gymnosperms are called:
| 1. | Archegonia | 2. | Female strobili |
| 3. | Megasporangium | 4. | Megasporophyll |
The bryophytes are also called as the amphibians of plants kingdom mainly because:
| 1. | they respire through the moist epidermis |
| 2. | they depend on water for sexual reproduction |
| 3. | they require more water than most plants |
| 4. | they lack true roots |
Vegetative reproduction in mosses is by:
| 1. | Fragmentation and budding in secondary protonema |
| 2. | Only budding in secondary protonema |
| 3. | Adventitious roots and budding in secondary protonema |
| 4. | Fragmentation and budding in sporophyte |
