For showing the detailed structure of food factory of plants, i.e., where the photosynthesis takes place. Designed after the latest electron microscopy interpretation of the chloroplast, the 3-dimensional structure is depicted in longitudinal and cross section to show the interior details of the chloroplast comprehensively enlarged about 60,000x. One quarter of the model is cut away to reveal the inner detail in three levels, which can be taken apart. This two part three-dimensional model of a chloroplast allows easy disassembly and removal of the thylacoids and linking stoma to reveal the interior structure where photosynthesis occurs. The complete model is mounted on a stand with numbered key card.
