In ginger vegetative propagation occurs through:
A technique of micro-propagation is:
Monoecious plant of Chara shows the occurrence of:
| 1. | Stamen and carpel of the same plant |
| 2. | upper antheridium and lower oogonium on the same plant |
| 3. | upper ooganium and lower antheridium on the same plant |
| 4. | antheridiophore and archegoniophore on the same plant |
Meiosis takes place in:
| 1. | Conidia | 2. | Gemmule |
| 3. | Megaspore | 4. | Meiocyte |
