Answer
Rain water
Reason — When raisins are placed in rain water, they absorb water through osmosis as rain water is a dilute solution in comparison to the contents of raisins. In saline water and saturated sugar solution, water moves out of the raisins by osmosis because these solutions are more concentrated; hence, the raisins do not swell and may shrink. Mustard oil 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.
