Answer 1

Answer:

ans b is correct

Explanation:

Answer 2

The correct solution is Option d.

• Runner is an example of vegetative propagule.It is a sub-aearial stem modification and classified under vegetative propogation through stems.
• Vegetative propagation is a kind of asexual reproduction that occurs through the vegetative structures like root,stems,leaves and nodes.
• The progeny produced is a clone of the parent plant i.e genetically and morphologically similar to the parent plant.
• Vegetative propagules are rich with meristems and can divide continuously to form new tissues.
• Runners grow horizontally on the ground and new plants arise from the specific regions where nodes are present.
• Later this nodes develop into buds and differentiate to produce adventitious roots and other organs to give rise a whole plant.
• Examples are Strawberry, Cyanodon, Bermuda Grass etc.
• This method is advantageous in the case of plants not producing seeds via sexual reproduction.
