Answer
Rain water
Reason — When raisins are placed in rain water, they absorb water through Osmosis as rain water serves as a dilute solution in comparison to the contents of raisins. In case of saline water and saturated sugar solution, they are more concentrated than the raisins hence Osmosis doesn't take place. As Mustard oil is not water, so it is not absorbed by the raisins.

If the xylem vessels of a plant are plugged:
- The leaves will turn yellow
- No food will be made
- The plant will wilt (shrivel)
- The plant will continue to grow
Force responsible for the ascent of sap is:
- Capillary force
- Root pressure
- Transpirational pull
- All the three
The root hairs are suited for absorbing water from the soil because:
- They have a large surface area
- They have a semi-permeable membrane
- They contain a solution of higher concentration than the surrounding water.
- All the three.
Transpiration is defined as:
- the rise of water up to the stem of a plant.
- the elimination of water with dissolved water products.
- the loss of water as water vapour from the aerial parts of a plant.
- the loss of water as water vapour from the roots as well as the leaves of the plant.
