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.
Palisade cells are responsible for most of the photosynthesis in the leaf. They are packed tightly together to maximize the amount of light they can absorb.
Because of lower epidermis the palisade layer packed so tightly together

Endothelial cells form the vascular network but acquire very different characteristics depending on their location. In the brain, endothelial cells are tightly packed to provide the brain-blood barrier that protects the brain from blood toxins. In the endocrine gland, endothelial cells are leaky and cause fenestrations to allow hormone trafficking throughout the body. In general, how tightly packed vascular network cells are depends on which area they are located.
in eukaryotic cells the DNA is very tightly packed to form strands of chromatin in the nucleus. in turn, the chromatin condenses (i.e. comes together) to form 'X' shaped chromosomes.
Single molecules of DNA are long and stringy. Each cell of your body contains six feet of DNA, but it's only one-millionth of an inch wide. To fit all of this DNA into your cells, it needs to be packed efficiently. To solve this problem, DNA twists tightly and clumps together inside cells. Even when you extract DNA from cells, it still clumps together, though not as much as it would inside the cell.
A plant's epidermis is primarily used for protective purposes, which it does by acting as a barrier to invaders (such as fungi). Another important function is in the prevention of water loss (for this reason, epidermal cells are packed tightly together). This water loss is further prevented by the waxy cuticle layer many plants have, located above the epidermal cells.

The cells of bread mold are loosely arranged. This is the opposite of the cells of mushrooms which are packed tightly 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?

Epithelial tissues are sheets of tightly packed cells that line organs and body cavities.
