Holdfast, stipe and frond constitutes the plant body in case of
| 1. | Rhodophyceae | 2. | Chlorophyceae |
| 3. | Phaeophyceae | 4. | All of these |
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

2. gymnosperms
3. monocots
4. bryophytes
A prothallus is
| 1. | a structure in pteridophytes formed before the thallus develops |
| 2. | a sporophytic free living structure formedin pteridophytes |
| 3. | a gametophyte free living structure formed in pteridophytes |
| 4. | a primitive structure formed after fertilisation in pteridophytes |
Plants of this group are diploid and well adapted to extreme conditions. They grow bearing sporophylls in compact structures called cones. The group in reference is
1. monocots
2. dicots
3. pteridophytes
4. gymnosperms
Protonema is
| 1. | haploid and is found in mosses |
| 2. | diploid and is found in liverworts |
| 3. | diploid and is found in pteridophytes |
