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.

Really, it is so the leaf can breathe.

Why does the middle of the leaf (the spongy region) have loosely arranged cells?
The spaces between the spongy mesophyll cells permit gases to move around within the leaf. That is why they are loosely arranged.
What are the loosely packed photosynthetic cells in the leaf called?
Thylakoids. Stacks of these are called granna.
Why spongy layer of cells loosely arranged?
So that the cell can breath.
Why are the cells of the palisades layer packed so tightly togehter?
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.
What is spongy mesophyll layer?
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 lower portion of the mesophyll usually consisting of loosely packed spherical cells?
spongy layer

Why are the cells of the spongy layer packed so loosly together?
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?
How are the cell of a bread mold arranged?
The cells of bread mold are loosely arranged. This is the opposite of the cells of mushrooms which are packed tightly together.
What Is the dfference between paliside and spongy?
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.
Prokaryotic cells I do not have a nuclear us so I am the result of loosely packed DNA who am I?
Loosely packed DNA can result in genes not being expressed properly.
Are loosely packed so air can move between the cells?
true

Thylakoids. Stacks of these are called granna.
Why spongy layer of cells loosely arranged?
So that the cell can breath.
How does the structure of spongy bone follow its function?
Spongy bone is porous and constructed of loosely connected structures. The spongy bones allows for the development of bone marrow. The main function of bone marrow is to produce blood cells.
How does the structure of SPONGY-BONE follow its function?
