Palisade Mesophyll

What is Palisade Mesophyll?

The layer of tall, closely packed, column-shaped cells lying immediately beneath the upper epidermis of a leaf. Palisade cells contain more chloroplasts than any other cell type in the leaf, and their position just below the transparent upper tissues means they receive the most light, so most of the leaf's photosynthesis takes place there.

This definition is part of the Plant Nutrition chapter in Cambridge O Level Biology.
