  Plant and Animal Classification Basics

  The NCERT biology basics tested in Environment: the plant kingdom's five divisions, flowering-plant morphology from root to flower, three Indian plant families by their floral characters, the criteria that sort animal phyla, and the four classes of fungi.

• Science & Technology

  Microbes, Immunity and Modern Biotechnology

  How NCERT links three topics: microbes as an industrial workforce, the immune system's B and T cells, and biotech tools like Bt cotton and gene therapy.
