RACHISES Meaning and
Definition
-
Rachises is a noun that refers to the central axis or stalk of a compound leaf or feather; it is also known as the main stem or midrib. In botany, the rachis is the extension of the petiole (the leaf stalk) that connects the leaflets or the individual blades of a compound leaf. It serves as a support structure, providing a pathway for the movement of water, nutrients, and sugars between the leaflets and the rest of the plant.
The rachis plays a crucial role in the overall structure and functioning of compound leaves. It is typically more rigid and durable compared to the petioles and leaflets, allowing the leaf to remain held up and exposed to sunlight. The rachis helps distribute resources, facilitating efficient photosynthesis and contributing to the overall health and growth of the plant.
In the case of feathers, the rachis is the main shaft from which the individual barbs, barbules, and other feather components arise. It provides stability and support, allowing the feathers to form the characteristic shape that aids in flight, insulation, and display.
The term "rachises" is the plural form of "rachis," used to refer to multiple central axes or stalks in the context of leaves or feathers.
