PERIPHYSIS Meaning and
Definition
-
Periphysis refers to a structure found in certain plants, particularly among gymnosperms, which serves as a specialized meristem responsible for secondary growth and the development of lateral organs. This term is derived from the Greek words "peri," meaning around, and "physis," meaning growth or nature. It can also be referred to as a lateral meristem.
The periphysis is distinct from the apical meristem, which is responsible for primary growth and the elongation of the plant. It typically exists in the form of a cylindrical sheath that surrounds the plant stem, enabling the growth and production of branches, leaves, and reproductive structures. This structure undergoes activity whenever the plant requires an increase in size or needs to accommodate new organs.
During secondary growth, the periphysis generates new cells through mitosis, allowing for the expansion of tissues in diameter. The newly formed cells differentiate into various types, such as xylem and phloem cells, enabling the transport of water, nutrients, and sugars throughout the plant. In some plants, the periphysis also produces cork cells, which form an outer protective layer known as the periderm.
The periphysis plays a crucial role in the overall growth and development of plants, contributing to their structural integrity and ability to adapt to changing environmental conditions. It is an essential component for plants that experience continuous growth throughout their lifespan and is vital for their overall survival and reproductive success.
