AIR VESICLE Meaning and
Definition
-
An air vesicle refers to a small sac or cavity found in certain aquatic plants, specifically those belonging to the family Hydrocharitaceae. These air-filled structures are commonly present in plants growing in submerged or floating habitats, aiding in their buoyancy and growth. Also known as air bladders or air sacs, air vesicles play a vital role in providing stability and ensuring the plants' exposure to sunlight for photosynthesis.
The air vesicles are primarily composed of spongy tissues that contain large air spaces. These spaces are filled with gases, primarily oxygen, which is obtained from the surrounding water through a specialized tissue called aerenchyma. The aerenchyma tissue transports oxygen from the leaves to the air vesicles, allowing gas exchange to occur between the plant and its environment.
The presence of air vesicles enables aquatic plants to stay afloat on the water's surface. By providing buoyancy, these structures keep the leaves and flowers of submerged plants above water, facilitating optimal sunshine exposure for photosynthesis. Additionally, air vesicles aid in nutrient uptake from the water and offer protection against being submerged or damaged during heavy rainfall or fluctuations in water levels.
In summary, air vesicles are small sac-like structures that provide buoyancy and stability to aquatic plants, allowing them to remain on the water's surface. These air-filled cavities facilitate gas exchange, aid in photosynthesis, and offer protection against environmental changes.

Etymology of AIR VESICLE
The word "air vesicle" is composed of two parts: "air" and "vesicle".
"Air" comes from the Old English word "ǣr", which means "air" or "wind". It can be traced back to the Proto-Germanic word "*awiz", derived from the Proto-Indo-European root "*h₂ewH-" meaning "to blow" or "breathe".
"Vesicle" comes from the Latin word "vesicula", which means "small bladder" or "little bag". It stems from the Latin word "vesica", meaning "bladder" or "cyst".
Therefore, combining "air" and "vesicle", we get "air vesicle" referring to a small bladder-like structure filled with air.
