Trees in Mediterranean region have thick bark.
Reason (R) :
It is an adaptation to long summer drought.
Answer: Option B
Answer: (b)
Long roots, thick bark and small-sized thick leaves are some of the adaptations among the plants to withstand a long dry season. Thick bark and small-sized leaves reduce the rate of transpiration.
Long roots enable plants to obtain moisture from great depth. The Mediterranean region does not receive rainfall in summers.
During winters when the pressure and wind belts shift towards the equator, these regions come under the influence of westerlies which blows from ocean to land which causes rainfall along the western margins.
