aciculas

Aciculas are small, stiff, needle-like structures found in plants, particularly in some gymnosperms. These structures are essentially modified leaves. The term "acicula" is Latin for "little needle." They are typically found in clusters along the stems of plants, serving a photosynthetic function. The shape and arrangement of aciculas can vary between different species, aiding in plant identification. For example, conifers often possess aciculas that are long and slender, while some other plants might have shorter, more robust ones. Their primary role is to capture sunlight for photosynthesis, and their morphology is often adapted to reduce water loss, especially in arid environments. The presence and characteristics of aciculas are a notable feature in the study of plant anatomy and taxonomy.
