Biofilm Capsid Pilus Envelope Fimbriae 17) How can a bacterium directly uptake a DNA molecule from the surrounding environment Conjugation Flagellum Transduction Transformation 18) Which slimy structure enables some individual bacteria to attach to host cells, reduce dehydration, and avoid the human immune system? Capsid Capsule Cell Wall Envelope Fimbriae 19) After perceiving unfavorable environmental conditions, what rotating structure enables prokaryotes to move away from such conditions? Capsule Envelope Flagellum Gas Vesicle 20) Which statement is true? Prokaryotic micro-compartments are surrounded by membranes Eukaryotic organelles typically are surrounded by a protein shell Eukaryotic cells typically are larger than most prokaryotic cells Prokaryotic cell membranes dont perform intra-cellular functions None of the above

Explanation / Answer

16) The complex extracellular prokaryotic structure that complicates antibiotic treatment and contaminates surfaces is known as biofilm. (option 1). Biofilms are implicated in various diseases like bacterial vaginosis, urinary tract infections, catheter related infections and middle ear infections.

All other options given in the question form a part of prokaryotic cell.
