Solution
The correct option is D thick cuticle
Conifer trees live in cold climates with lots of snow and less water. One of the most important adaptations of conifer trees is the thick waxy cuticle. The cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss.
Conifers are gymnosperms and lack vessels. Needle-shaped leaves of gymnosperms are adapted not to accumulate much snow, the presence of waxy cuticle and sclerenchyma protect the underlying mesophyll cells, tightly packed tissues protect the central vein containing vascular tissues.
Thus, these leaves are well adapted to withstand the harsh and cold climate. They have sunken stomata to preserve water loss during physiological drought conditions.
So, the correct answer is 'Thick cuticle'
