1. Gelidium and Gracilaria
2. Anabaena and Volvox
3. Chlorella and Spirulina
4. Laminaria and Sargassum
Phycoerythrin is the major pigment in:

1. They are heterosporous
2. Male and female gametophytes are free-living
3. Most of them have narrow leaves with thick cuticles
4. Their seeds are not covered
Read the following five statements (I - V) and answer as asked next to them.
| I. | In Equisetum, the female gametophyte is retained on the parent sporophyte |
| II. | In Ginkgo, male gametophyte is not independent |
| III. | The sporophyte in Riccia is more developed than that in Polytrichum |
| IV. | Sexual reproduction in Volvox is isogamous |
| V. | The spores of slime molds lack cell walls |
How many of the above statements are correct?
| 1. Three | 2. Four |
| 3. One | 4. Two |
Which one of the following pairs is wrongly matched?
1. Salvinia - Prothallus
2. Viroids – RNA
3. Mustard-Synergids
4. Ginkgo-Archegonia
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 |
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. |
Match items in Column I with those in Column II:
| (A) | Peritrichous flagellation | (J) | Ginkgo |
| (B) | Living fossil | (K) | Macrocystis |
| (C) | Rhizophore | (L) | Escherichia coli |
| (D) | Smallest flowering plant | (M) | Selaginella |
| (E) | Largest Perennial alga | (N) | Wolffia |
Select the correct answer with the following
1. A –L ; B –J; C –M ; D – N ; E – K
2. A– K ; B – J; C – L ; D –M; E – N
3. A– J ; B – K; C – N ; D –L; E – K
4. A– N ; B – L; C – K ; D – N; E –J
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 |
