All plant cells respire all of the time and need to exchange gases. The main gas exchange surface in plants are the spongy mesophyll cells in the leaves. Leaves have a huge surface area, and the irregular-shaped, loosely-packed spongy cells increase the area for gas exchange even more.
The spaces between the spongy mesophyll cells permit gases to move around within the leaf. That is why they are loosely arranged.
The spongy layer is located beneath the upper epidermis in the mesophyll tissue of plant leaves. It is made up of loosely packed cells with air spaces between them, allowing for gas exchange and photosynthesis to occur more efficiently.
Thylakoids. Stacks of these are called granna.
Spongy tissue in leaves has loosely packed cells with large air spaces between them, facilitating gas exchange. In contrast, other leaf tissues like palisade mesophyll have tightly packed cells arranged in columns for efficient photosynthesis. Spongy tissue is located beneath the palisade layer and aids in maximizing gas diffusion within the leaf.
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.

Because you cannot live in them. For instance, if they were packed tightly together, they would be called apartments. My question is why are they called apartments when they are all stuck together?
The cells of bread mold are loosely arranged. This is the opposite of the cells of mushrooms which are packed tightly together.
Beneath the palisade layer of a leaf is the spongy mesophyll layer. This layer contains loosely packed cells with air spaces between them that allow for gas exchange, such as the intake of carbon dioxide and the release of oxygen during photosynthesis.
Loosely packed DNA can result in genes not being expressed properly.
