Meso- means middle. So mesophyll are the cells found in the middle of the leaf between the upper and lower epidermis.
Mesophyll cells having chloroplasts are called chlorenchyma.
The two types of photosynthetic mesophyll are -- (i) Palisade cells which are vertically elongated cylindrical cells and (ii) Spongy mesophyll cells that are spherical green cells.
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.

The palisade mesophyll organ belongs to the leaf organ.

Cytoplasm of the mesophyll cells
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.
Guard cells , spongy mesophyll layer and upper epidemic
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.
they are the objects inside a cross-section of a leaf which are loosley packed cells that give the leaf a spongy appearence.
What would be the advantages to having no chloroplasts in the cells of the spongy mesophyll? Fewer chloroplasts in the spongy mesophyll because most of the light energy is absorbed by the chloroplasts of the palisade mesophyll. ... They waxy cuticle keeps water inside the leaf cells.
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.
