PALISSADE TISSUE Meaning and
Definition
-
Palissade tissue, also known as palisade parenchyma, refers to a specialized type of plant tissue found in the leaves of higher plants. It is responsible for carrying out pivotal functions related to photosynthesis. The term "palissade" originates from the French word "palisade" meaning "paling" or "fence," which aptly describes the linear arrangement and tightly packed nature of the cells in this tissue.
Palissade tissue is predominantly located in the upper layer of a leaf's mesophyll and can often be identified as a distinct region, especially in dicotyledonous plants. The cells in palissade tissue are elongated and cylindrical, closely packed together in parallel rows, creating a "fence-like" appearance. This ordered cellular arrangement optimizes the absorption of incident light for photosynthesis by maximizing the surface area available for chloroplasts.
The primary function of palissade tissue is to perform photosynthesis, the process by which plants convert light energy into chemical energy to fuel their growth and development. The chloroplasts present in these cells contain chlorophyll pigments, which capture light energy and convert it into chemical energy. Palissade tissue is particularly efficient in this process due to its proximity to incident light and the high concentration of chloroplasts within its cells.
Overall, palissade tissue plays a crucial role in maximizing photosynthesis efficiency in plants, ensuring optimal energy production for growth and metabolism.

Etymology of PALISSADE TISSUE
The word "palissade tissue" is derived from the French term "palissade", which means "paling" or "fence". It refers to a form of plant tissue found in the stems and roots of many dicotyledonous plants. The term "palissade tissue" was first introduced in botany to describe a type of specialized tissue found in the leaves of certain plants. This tissue is located beneath the epidermis and is composed of elongated, densely packed cells arranged vertically. It plays a role in the support and mechanical strength of the leaf.
