GROWING POINT Meaning and
Definition
-
Growing point is a term used in biology and botany to describe the specific area in a plant where active cell division and expansion occur, leading to the growth and development of various plant structures. It is the site where new tissues and organs such as stems, leaves, and flowers are produced.
The growing point is typically located at the apex or tip of the plant, and it is responsible for the plant's ability to increase in size and complexity. It contains a group of undifferentiated cells, known as meristematic cells, which have the capacity to divide and give rise to different types of specialized cells.
The primary meristems found in the growing point are responsible for primary growth, which includes elongation of the stem, formation of new leaves, and establishment of the root system. These meristems produce various tissues such as epidermis, cortex, and vascular tissues.
Secondary meristems, also known as the vascular cambium and cork cambium, are located in the growing point as well. They are responsible for secondary growth, which involves an increase in girth or thickness of the plant. The vascular cambium produces secondary xylem (wood) and secondary phloem, while the cork cambium produces protective cork tissue.
Overall, the growing point plays a crucial role in the overall growth and development of plants. It is a dynamic area where cell division, elongation, and differentiation occur, enabling the plant to adapt and respond to environmental cues while continually expanding in size and complexity.

Etymology of GROWING POINT
The word "growing point" is composed of two individual words: "growing" and "point".
The term "growing" comes from the verb "grow", which originated from the Middle English word "growen", and before that, from the Old English word "grōwan". The Old English word is related to the Proto-Germanic word "grōan", meaning "to grow, enlarge". Its further origins can be traced back to the Proto-Indo-European root "*geh₂u-", which carries the sense of "to grow".
The word "point" comes from the Old French word "pointe", which translates to "sharp end, tip, or point". It is derived from the Latin word "puncta", meaning "pointed end".
