Monera

In this Class 9 Science topic from “Patterns in Life: Diversity and Classification,” students explore Monera as a major group of mostly unicellular, prokaryotic organisms. They learn how bacteria differ from organisms with a true nucleus and membrane-bound organelles, and examine their cell structure, varied shapes, nutrition, respiration, reproduction, and habitats. The topic also introduces useful and harmful bacteria, helping students understand their roles in decomposition, food production, disease, and the balance of ecosystems.
