WebThe invaginated section, with the pathogen inside, pinches off from the plasma membrane to form a structure called a phagosome. The phagosome then fuses with a lysosome, forming a combined compartment where digestive enzymes destroy the pathogen. Vacuoles Plants cells are unique because they have a lysosome-like organelle called the vacuole. WebThe simplest mechanism by which molecules can cross the plasma membrane is passive diffusion. During passive diffusion, a molecule simply dissolves in the phospholipid bilayer, diffuses across it, and then …
