Final answer:
True. Plant anatomy can be used to determine past climates and in forensic science.
Step-by-step explanation:
True.
Knowledge of plant anatomy can help in determining past climates and in forensic science. By studying plant fossils, paleobotanists can analyze the characteristics of ancient plants to understand environmental conditions in the past. This information can then be used to reconstruct past climates. Additionally, plant anatomy can be utilized in forensic science to identify plant materials found at a crime scene, such as pollen or plant fragments, which can provide clues about the location or time of the crime.
