PALISADE CELL Meaning and
Definition
-
A palisade cell is a type of specialized plant cell that is found in the mesophyll layer of leaves. These cells are vertically elongated and are arranged closely together in a compact manner, resembling a palisade fence, hence the name. The palisade cells are primarily responsible for carrying out photosynthesis, the biological process through which plants convert sunlight into chemical energy to produce food.
The structure of palisade cells is optimized for their vital role in capturing and utilizing sunlight. These cells contain a large number of chloroplasts, which are responsible for carrying out photosynthesis. The chloroplasts are densely packed and are located near the top of the cell, as this is where the maximum amount of sunlight is available. The close proximity of the chloroplasts to each other ensures efficient absorption of light energy.
Furthermore, palisade cells are characterized by their abundant presence of cytoplasm, which is rich in nutrients and enzymes needed for photosynthesis. The presence of a large central vacuole provides structural support to the cell and regulates its functions.
The shape and arrangement of palisade cells optimize their light absorption capacity, as they are oriented perpendicular to the surface of the leaf. This arrangement helps in maximizing the capture of sunlight for photosynthesis, contributing to the plant's overall energy production.
In summary, palisade cells are specialized plant cells found in leaf mesophyll. They are elongated, closely packed, and rich in chloroplasts, supporting the essential process of photosynthesis. Their structure and arrangement are adapted to maximize light absorption, enabling plants to efficiently convert sunlight into energy.

Etymology of PALISADE CELL
The word "palisade" can be traced back to the Middle French word "palissade", which originated from the Italian word "palissada" or "palificata". In turn, the Italian term came from the Latin word "pālus" meaning "stake" or "post". A "palisade" originally referred to a fence or fortification made of wooden stakes or poles placed closely together.
The term "cell" comes from the Latin word "cella" meaning "small room" or "storeroom". In the context of biology, it refers to the basic structural and functional unit of all living organisms.
When combined, "palisade cell" refers to a specialized plant cell found in the leaves. These cells are elongated, column-like, and closely packed together, resembling a palisade fence or fortification.
