What layer of leaf is responsible for photosynthesis?
A - Cuticle
B - Palisade layer
C - Stomata
D - Spongy layer
Answer: B - Palisade layer
The PALISADE LAYER is the location of photosynthesis. Below it is the spongy layer which contains cells that are more spread out, allowing for air pockets, and there are vascular bundles that contain xylem and phloem, allowing for the transport of products for photosynthesis. Together these are known as the MESOPHYLL.
