Chloroplast
It is the spongy layer inside plants.
This answer refers to the cell layers of a plant leaf: There's the outer cuticle, the upper epidermis, the palisade mesophyll cell, the bundle sheath cell (containing xylem and phloem) surrounded by spongy mesophyll cells and then the lower epidermis. Not sure if this helps...
Spongy Layer - A layer of the mesophyll. The spongy layer consists of chloroplasts and parenchyma cells, and relatively large intercellular spaces. It is far less ordered than the palisade layer, and the intercellular spaces are important in gas exchange and transpiration.
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.
Mesophyll tissue forms the bulk of the leaf. It makes up the green tissue of the leaf and consists of thin-walled cells containing chloroplasts (bits that contain the chlorphyll). In most dicot plants, the mesophyll is differentiated into palisade parenchyma and spongy parenchyma. The palisade parenchyma consists of thin-walled cells which are usually cylindrical. These cells contain large numbers of chloroplasts - the organelle used for capturing light and subsequesnt photosysnthesis.The spongy prenchyma, however, contains far fewer chloroplasts, so its main function is not photosynthesis. The spongy parenchyma has an open and net-like structure with large inter-cellular spaces that facilitate gas diffusion. The major function of the spongy parenchyma is the transport of oxygen, carbon-dioxyde and water vapour. It also is involved in the transport of water and the products of photosynthesis, the sugars. The spongy parenchyma is in close connection with the vascular bundles and the palisade parenchyma. When no clear differentiation exists between palisade and spongy parenchyma, the tissue is called mesophyll.Read more: http://wiki.answers.com/Why_is_the_palisade_layer_where_most_photosynthesis_occur#ixzz18UOwDLzu

Yes
The palisade layer and the spongy layer.
The mesophyll tissue of the leaf contains chloroplasts as it is responsible for photosynthesis. In addition, the guard cells of the stomata also contain chloroplasts to help regulate gas exchange.
Spongy Layer
The palisade layer of the leaf contains the most chloroplasts. This layer is positioned right below the upper epidermis and is responsible for the majority of photosynthesis due to its high concentration of chloroplasts.

The palisade layer contains more chloroplasts than the spongy layer and therefore photosynthesises more. Photosynthesis is the plants process of making energy and so the palaside layer makes more food (glucose) than any other layer.
the palisade layer, spongy layer
Spongy Layer - A layer of the mesophyll. The spongy layer consists of chloroplasts and parenchyma cells, and relatively large intercellular spaces. It is far less ordered than the palisade layer, and the intercellular spaces are important in gas exchange and transpiration.
The mesophyll has two layers. The outermost layer is the palisade layer that is made of tightly packed chloroplasts, and the innermost layer is the "spongy layer" that has air between its cells.
