When bacilli in a chain fold back upon each other like a hinge, this cellular arrangement is termed a Palisades

Palisade cells are plant cells that located on the leaves, below the epidermis and cuticle. Palisade cells are vertically elongated. The chloroplasts in these cells absorb a major portion of the light energy used by the leaf. Palisade cells are found in the mesophyll of a leaf and their main function is in the absorption of light so that photosynthesis can take place.

The palisade layer contains the most chloroplasts as it is near the top of the leaf. The chloroplasts contain the pigment chlorophyll. The palisade cells are arranged upright. The arrangement of Palisade cells is important because the spongy layer contains fewer chloroplasts, that is enough to catch what the palisade layer cannot absorb.

The bacilli bend at the points of division following the cell divisions, resulting in a palisade arrangement resembling a picket fence and angular patterns that look like Chinese letters.

Hope it helps!
