1. Leafy gametophyte
2. Prothallus
3. Sporophyll
4. Protonema
A feature common in gametophyte of both mosses and maximum ferns is-
1. Independent existence
2. Both are monoecious in nature
3. Presence of vascular tissue
4. Both are filamentous
In ferns, fertilization does not involve:
| 1. | Archegonia | 2. | Water |
| 3. | Pollen tube | 4. | Flagellated antherozoids |
Read the statement (a - d) :
| a. | The male and female gametophytes do not have independent existence. |
| b. | The multicellular female gametophyte is also retained within megasporangium. |
| c. | The gametophytic generation is reduced. |
| d. | Sporophylls are aggregate to form cone like structures. |
The above statements belong to which group of plant kingdom?
| 1. | Bryophytes | 2. | Pteridophytes |
| 3. | Gymnosperms | 4. | Angiosperms |
The unbranched stem is character of which gymnosperm:-
| 1. | Pinus | 2. | Cycas |
| 3. | Cedrus | 4. | Lycopodium |
Read the following statements :
| (a) | More than one Archegonia |
| (b) | Show symbiotic associated with Nitrogen fixing Cyanobacteria and fungus |
| (c) | Show heterosporous nature |
| (d) | Reduced male gametophyte is called a pollen grain |
The above statement is related to which option?
| 1. | Bryophytes |
| 2. | Gymnosperms |
| 3. | Pteridophytes and Gymnosperm |
| 4. | Gymnosperm and Angiosperm |
