Palisade Cells

Palisade cells are a dense layer of cylindrical cells in the mesophyll located near the epidermis of the upper side of the leaf. These elongated cells fit tightly to each other, forming a compact layer resembling a palisade.

Palisade cells play an important role in photosynthesis. They contain large amounts of chloroplasts and pigments such as chlorophyll. Their elongated shape and dense arrangement allow them to effectively absorb light energy necessary for photosynthesis. In addition, palisade cells regulate leaf gas exchange by exchanging oxygen and carbon dioxide through stomata on the upper surface of the leaf.

Thus, palisade cells play a key role in the life of the plant, ensuring its photosynthesis and gas exchange. Their special structure and organization are aimed at performing these important functions as efficiently as possible.
