Q. No.
Examine the figure given below and select the right option giving all the four parts (A, B, C and D) correctly identified:
| A | B | C | D | |
| 1. | Antheridiophore | Male thallus | Globule | Roots |
| 2. | Archegoniophore | Female thallus | Gemma cup | Rhizoids |
| 3. | Archegoniophore | Female thallus | Bud | Foot |
| 4. | Seta | Sporophyte | Protonema | Rhizoids |
Selaginella and Salvinia are considered to represent a significant step towards the evolution of seed habit because:
| 1. | Embryo develops in female gametophyte which is retained on parent sporophyte. |
| 2. | Female gametophyte is free and gets dispersed like seeds. |
| 3. | Female gametophyte lacks archegonia. |
| 4. | Megaspores possess endosperm and embryo surrounded by a seed coat. |
Examine the figures A, B, C and D. In which one of the four options all the items, A, B, C and D are correct?
Options :
| A | B | C | D | |
| 1. | Equisetum | Ginkgo | Selaginella | Lycopodium |
| 2. | Selaginella | Equisetum | Salvinia | Ginkgo |
| 3. | Funaria | Adiantum | Salvinia | Riccia |
| 4. | Chara | Marchantia | Fucus | Pinus |
Which one of the following pairs is wrongly matched?
1. Salvinia - Prothallus
2. Viroids – RNA
3. Mustard-Synergids
4. Ginkgo-Archegonia
Given are the following five statements (I - V) for your consideration:
| I: | In Equisetum, the female gametophyte is retained on the parent sporophyte |
| II: | In Ginkgo, male gametophyte is not independent |
| III: | The sporophyte in Marchantia is more developed than that in Polytrichum |
| IV: | Sexual reproduction in Volvox is isogamous |
| V: | The spores of slime moulds lack cell walls |
How many of the above statements is/are correct?
| 1. | Three | 2. | Four |
| 3. | One | 4. | Two |

1. Spirogyra -Motile gametes
2. Sargassum - Chlorophyll C
3. Basidiomycetes - Puffballs
4. Nostoc- Water blooms
1. Presence of archegonia
2. Well-developed vascular tissues
3. Independent gametophyte
4. Independent sporophyte
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 |
