Why are desert plants able to survive in arid conditions with thick, waxy coatings on their leaves?
- A. To increase photosynthesis
- B. To prevent water loss through transpiration
- C. To provide mechanical support
- D. To increase rate of respiration
Answer: B. To prevent water loss through transpiration

Sclerenchyma cells are dead and provide strength to plants. How is this achieved?
- A. By storing starch
- B. By having thin cellulose cell walls
- C. By having walls thickened due to lignin deposition
- D. By actively dividing to create new layers
Answer: C. By having walls thickened due to lignin deposition
