Question

which structure helps prokaryotes attach to surfaces and form biofilms? endospores pili (fimbrae) flagella inclusion bodies question 51 (bonus) (1 point) select what is true of prokaryotic cells. select all that apply. differentiated by cell shape and arrangement contain no membrane bound organelles have a main nucleus contain 70 s robosomes often have plasmids

Explanation:

Pili (fimbrae) are hair - like appendages that help prokaryotes attach to surfaces and form biofilms. Prokaryotic cells are differentiated by cell shape and arrangement (e.g., cocci, bacilli, spirilla), lack membrane - bound organelles, do not have a main nucleus (they have a nucleoid), contain 70S ribosomes, and often have plasmids.

Answer:

First question: B. Pili (fimbrae)
Second question:
Differentiated by cell shape and arrangement
Contain no membrane bound organelles
Contain 70 S ribosomes
Often have plasmids
