Transmission tissue is a characteristic feature of:
Which of the following are the important floral rewards to animal pollinators?
Geitonogamy involves:
| 1. | Pollination of a flower by the pollen from another flower of the same plant. |
| 2. | Pollination of a flower by the pollen from another same flower. |
| 3. | Pollination of a flower by the pollen from a flower of another plant in the same population. |
| 4. | Pollination of a flower by the pollen from a flower of another plant belonging to a distant population. |
Pollen tablets are available in the market for:
| 1. | In vitro fertilization | 2. | Breeding programmes |
| 3. | Supplementing food | 4. | Ex-situ conservation |
Function of filiform apparatus is to:
| 1. | Recognize the suitable pollen at the stigma |
| 2. | Stimulate division of generative cell |
| 3. | Producer nectar |
| 4. | Guide the entry of the pollen tube |
Non- albuminous seed is produced in:
| 1. | Maize | 2. | Castor |
| 3. | Wheat | 4. | Pea |
| 1. | having no reserve food |
| 2. | being a diploid tissue |
| 3. | its formation by fusion of secondary nucleus with several sperms |
| 4. | being a haploid tissue |
Advantage of cleistogamy is:
1. More vigorous offspring
2. No dependence of pollinator
3. Vivipary
4. Higher genetic variability
