cell walls
ribosomes
submit request answer
part b
what is the function of a bacteriums capsule?
protection
protein synthesis
propulsion
dna storage

Explanation:

For Part A, fimbriae are hair - like appendages that help bacteria adhere to surfaces. Mitochondria are energy - producing organelles in eukaryotes (not relevant for bacteria in this context), flagella are for movement, cell walls provide structural support, and ribosomes are for protein synthesis.
For Part B, the capsule of a bacterium provides protection against phagocytosis and desiccation. Protein synthesis occurs at ribosomes, propulsion is by flagella, and DNA is stored in the nucleoid region.

Answer:

Part A. Fimbriae
Part B. protection
