Question

which adaptation would be beneficial for a plant that lives in a desert biome?
○ large, wide leaves
○ leaves with drip tips
○ deep roots
○ expandable stem

Explanation:

Desert plants need to conserve water. Large, wide leaves would lose too much water through transpiration. Leaves with drip tips are more common in rain - forest (to shed excess water). Deep roots can access water from deep underground. An expandable stem can store water. Both deep roots and expandable stem are adaptations for desert plants. But if we consider the options, deep roots help in getting water from deep soil layers (a key need in desert where surface water is scarce) and expandable stem helps in water storage.

Answer:

C. deep roots, D. expandable stem
