PLEURENCHYMA Meaning and
Definition
-
Pleurenchyma is a botanical term referring to a specialized type of tissue found in plants. It is a type of ground tissue, which means it is responsible for providing structural support in the plant's organs. Pleurenchyma is primarily found in the stems and leaves of plants, although it may also be present in other parts.
In terms of its structure, pleurenchyma is composed of elongated, spindle-shaped cells that are tightly packed together. These cells are characterized by having thick walls, which provide strength and durability to the tissue. The thick walls contain lignin, a complex organic polymer that adds rigidity and resistance to mechanical stress.
The main function of pleurenchyma is to provide support to the plant's organs, helping them maintain their shape and withstand external pressures. Its presence in stems, for example, helps the plant stand upright and prevents the collapse of the internal transport tissues. In leaves, pleurenchyma supports the lamina and helps to maintain the necessary structure for optimal photosynthesis.
Furthermore, pleurenchyma cells can also store water and nutrients, acting as reservoirs during periods of drought or nutrient scarcity. This feature contributes to the plant's ability to survive under adverse environmental conditions.
In summary, pleurenchyma is a specialized tissue that plays a crucial role in providing structural support to plants, facilitating their growth, and helping them adapt to environmental challenges.

Etymology of PLEURENCHYMA
The word "pleurenchyma" is derived from the combination of two Greek words: "pleura" meaning "side" or "rib" and "enchyma" meaning "infused" or "a poured in substance".
The term "pleurenchyma" is used in botany and refers to the specialized tissue found in plant leaves or stems that are involved in providing support and protection. This tissue is composed of elongated cells that are densely packed together, providing structural strength to the plant.
