MERISTEMATIC Meaning and
Definition
-
Meristematic, in the field of biology, refers to the characteristic of a tissue or cell that possesses the ability to undergo continuous growth and division, giving rise to new cells and promoting the growth and development of plants. It is derived from the term "meristem," which represents the actively dividing cells at the growing tips of roots and shoots.
Meristematic cells are found in regions of plant tissue where growth and cell division occur, known as meristems. These regions are responsible for the formation of new plant tissues and organs, leading to the growth and elongation of roots, stems, and leaves. Meristematic cells have the unique capability to divide and differentiate into a wide range of specialized cell types, enabling plants to grow in specific directions and respond to external stimuli.
The key characteristic of meristematic cells is their perpetual division and ability to produce more cells. They have a high metabolic rate and possess dense, distinct nuclei. Their cytoplasm is dense and rich in ribosomes, endoplasmic reticulum, and mitochondria, which are essential for cell division and growth.
Meristematic cells can differentiate into various types of cells, including the dermal, ground, and vascular tissues, which form the different organs and systems of the plant. These cells play a vital role in plant development, enabling the formation of new tissues, regeneration, wound healing, and the overall growth and differentiation of plants.

Etymology of MERISTEMATIC
The word "meristematic" comes from the Greek roots "meristos" meaning "divided, divisible" and "stema" meaning "thread" or "shoot". The term was coined by German botanist Heinrich Anton de Bary in 1884 to describe the type of plant tissue that is actively dividing and responsible for growth in plants.
