alleryWhich Selina experiment shows that only roots absorb water from soil?
ABalsam plants in marked tubes A, B, C, D
BVariegated leaf starch test with iodine solution
CHalf-leaf experiment using potassium hydroxide
DMohl's half-leaf experiment with sodium chloride
Answer & Solution
Correct answer: A. Balsam plants in marked tubes A, B, C, D
1. Activity 1 in the chapter uses four tubes A, B, C, D with balsam plants.
2. Tubes B and C have roots dipped in water; tube D does not.
3. Only the plants with dipped roots remain healthy after a day.
4. This shows roots, not stems or leaves, absorb water.
