they contain many more chloroplasts than other cells; chloroplasts contain the two chlorophyll pigments which are the photosystems that photons are passed to - this molecule reduces electron carriers that power the conversion of air and water to sugar. The photons obviously come from light waves hitting the leaves. Depending on a plants needs, which vary over a day or week, more or less photosynthesis will be required. It is important to realise that chloroplasts are mobile within the cell. Being elongate, the palisade cells are shaped to facilitate the movement of the chloroplasts towards the light when increased photosynthesis is required, (this then offers a maximum surface area for light absorption); and to allow the chloroplasts to move inward away from the light when PS is not required (thus decreasing the surface area which decreases the rate of PS).

The palisade cells have the largest number of the chlorophyll producing organelles - chloroplasts than any other cell in the plant. Chlorophyll traps light energy for use in breaking the water molecules [H2O] - photolysis.This is the first part of a chain of reactions referred to as Photosynthesis - which is the specific function of these cells.

Two specilizations, both of which are suited to allow maximum ammount of sunlight gathering.
1. Largest concentration of chloroplasts per cell is found in Palisade cells.
2. Elongated geometry with the orientation such that the sunlight passes through as many chloroplasts per cell as possible, thus maximixing light absorption.

Somone asked this a few days ago look at the resolved questions. Or read a textbook.
