Solution:
Statement (I) is correct. Desert plants have adaptations to minimize water loss, which include a thick cuticle on their leaf surfaces and sunken stomata (stomata arranged in deep pits) to reduce transpiration.
Statement (II) is incorrect. In desert plants likeOpuntia, the leaves are reduced to spines to minimize water loss. The photosynthetic function is taken over by the flattened, green stems (phylloclades).
Therefore, Statement (I) is correct but Statement (II) is incorrect.
