Answer:
1. a) When the raisin is dipped in plain water, the water molecules enter the raisin from the water as there are more amount of water molecules in water. The raisin becomes turgid.
b) When the raisin is dipped in sugar solution, the water molecules exit the raisin as there are more amount of water molecules in the raisin. The raisin becomes flaccid.
2. The process is osmosis.
