Which statement about leaves is correct?
A) The photosynthetic mesophyll is made up of an upper spongy layer and a lower palisade layer.
B) The epidermis is covered by a waxy layer of cuticle that reduces water loss.
C) Gas exchange occurs through tiny openings in the leaf surface called trichomes.
D) Vascular tissue is arranged in a net pattern in monocots and a parallel pattern in eudicots.
E) Regulation of gas exchange through the leaf is the responsibility of the bundle sheath cells.
Trichomes
Small hairs or other outgrowths from the epidermis of plants, often serving as defense against herbivores and reducing water loss.
Photosynthetic Mesophyll
The layer of cells in a leaf where most photosynthesis occurs, rich in chloroplasts.
Gas Exchange
The process by which oxygen is taken in and carbon dioxide is released out, occurring in the lungs and tissues or in the cells and environment for organisms.

Final Answer :
B
Explanation :
The epidermis of leaves is covered by a layer of cuticle that reduces water loss. This is an important adaptation for leaves that are exposed to sunlight and can easily lose water through transpiration. The cuticle is a waxy layer that covers the surface of the leaf and prevents water from escaping.
