CLASS-IX-CBSE-SCIENCE-Fundamental Unit Of Life-BIOLOGY 1) Differentiate Bacterial Cell from a Human Cell?    Cell Wall:     In bacteria cell thick defensive cell wall exists covering the entire cell.    In human cell, cell wall does not exist.   Cytoplasmic Bridge:     In bacterial cell, no cytoplasmic bridge exists  because there is just a single cell.    I n human cell, cytoplasmic bridges exist   which help in inner transportation of cell.    Shape :    Bacterial cell exists in many shapes such as circle, oval etc.    Human cell exists only in two shapes which are oval or   spherical.   Cell Membrane: In bacterial cell, cell membrane is fabricated of phospholipid bi-layer. But the membrane has no sterols. In human cell, cell membrane is fabricated of lipid bi-layer in the company of phosphate particles. It behaves as hydrophilic to outside and hydrophobic in the internal wall.     Cell Appendages: In bacterial cell, cell appenda
