How do scientists know about the structures of this ancient extinct plant?

Scientists learn about the structures of ancient extinct plants primarily through the study of fossilized remains, which can include leaves, stems, and reproductive structures. Techniques such as paleobotany, which involves analyzing these fossils, provide insights into their morphology and anatomy. Additionally, advanced imaging technologies like CT scans and electron microscopy allow for detailed examination of fossil structures at a microscopic level. This information, combined with comparisons to modern relatives, helps reconstruct the appearance and function of these ancient plants.
