The Spirogyra Model is a detailed three-dimensional representation of the filamentous green alga Spirogyra, designed for educational and laboratory purposes. It clearly illustrates key features such as spiral chloroplasts, cell wall, nucleus, pyrenoids, and cytoplasm, providing students with a visual understanding of its structure, reproduction, and photosynthetic functions. Made from durable, high-quality materials with distinct coloring, this model is ideal for classroom demonstrations, laboratory teaching, and interactive learning in botany and microbiology
