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 |
A true statement for Ulothrix:
| 1. | Filamentous thallus and flagellated reproductive structures |
| 2. | Branched thallus |
| 3. | Flagellated cells absent |
| 4. | None of the above |
In oogamy, fertilization involves:
| 1. | A large non-motile female gamete and a small motile male gamete |
| 2. | A large non-motile female gamete and a small non-motile male gamete |
| 3. | A large motile female gamete and a small non-motile male gamete |
| 4. | A small non-motile female gamete and a large motile male gamete |
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 |
