Palisade
Packing palisade cells tightly together means that the maximum amount of light can be intercepted. If there are big gaps between the cells then more of the light hitting the leaf will just pass straight through. Tightly packed palisade cells is one way in which leaves are adapted for photosynthesis.
In the palisade cells, spongy cells, and guard cells.
They do some photosynthesis, however not as much as palisade cells.
Mesophyll In between upper and lower epidermis of leaf is mesophyll tissue. In the dorsiventral leaves, mesophyll is divisible into upper palisade cells and lower spongy parenchyma. The palisade cells are mainly involved in photosynthesis and spongy parenchyma in gaseous exchange.
The palisade mesophyll is superior to the spongy mesophyll (in most leaves) which aids in photosynthesis, but also serves a "sun block" to the more sensitive cells the spongy mesophyll.

they are the objects inside a cross-section of a leaf which are loosley packed cells that give the leaf a spongy appearence.
Spongy mesophyll cells are not packed so tightly together, which allows carbon dioxide and oxygen to reach the palisade cells where they are needed in photosynthesis. Spongy mesophyll cells and guard cells (see below) also get some photosynthetic action.
Spongy Layer
The palisade layer of cells is tightly packed, like a brick wall, and contains the greatest concentration of chloroplasts in the leaf. The spongy mesophyll is loosely packed, containing many air spaces between the cells. The mesophyll contains vascular bundles and fewer chloroplasts than the palisade. Simply put, the palisade's main purpose is photosynthesis, and the spongy's gas exchange.
Palisade and spongy parenchyma in the leaves
Palisade mesophyll cells are tall and closely packed to absorb maximum light. They contain many chloroplasts. Most photosynthesis takes place in the palisade cells. Spongy mesophyll also captures light and makes food.
It would be the palisade cells.
