   Phospholipids (printed "Phospholids") form the plasma membrane of every cell, bacterial, plant and animal. Cellulose is a plant cell-wall material absent from animal cells, and histones are absent in bacteria. TSLPRB's final key keeps (4) but also gave the mark to candidates who left this question blank. (TSLPRB's final key also gave the mark to candidates who left this question unanswered.)
