Vacuoles in Bacteria Cells

• An important point to note as well is that vacuoles aren’t present in all bacterial cell types. Wherever they are present, their main function is storage as in animal cells.

Example:

• Some species of sulfur bacteria possess very large-sized vacuoles (taking up to 98% of the cell’s volume).
• Some species of cyanobacteria possess a special type of vacuole that is “permeable to atmospheric gases”.
