Cell: The Unit of Life
The cell is the smallest unit that can still be called alive. This chapter in NCERT Class 11 Biology, Chapter 8, compares prokaryotic and eukaryotic cells and tours the plasma membrane, wall, endomembrane system, mitochondria, plastids, ribosomes, cytoskeleton, cilia, flagella, nucleus and chromosomes. It explains the fluid mosaic membrane, transport, and how organelles divide labour. You will learn to use cell theory, estimate size with microscopy, and link each structure to its function in plant and animal cells.
