Ch-03: Cell
The cell is introduced as the fundamental unit of life. A detailed comparison of animal and plant cell structures is presented, including diagrams of organelles like the nucleus and mitochondria. The chapter outlines the structural advantages of plant cells (cell wall, chloroplasts) and animal cells
(centrioles). It identifies specialized cell types (neurons, muscle, RBCs) and explains the concept of division of labour across organelles and within multicellular organisms, culminating in a definition of stem cells as unspecialized precursor cells.#CellBiology #PlantCell #AnimalCell #Organelles #StemCells #Mitochondria #Nucleus #Biology #FBISE #Class9 #Science
