or more molecules combine to produce water or another simple molecule
Hydrolysis - 🧠ANSWER ✔✔Breaking down complex molecules by the
chemical addition of water
Nucleoid - 🧠ANSWER ✔✔A dense region of DNA in a prokaryotic cell.

separately from the bacterial chromosome
Ribosomes - 🧠ANSWER ✔✔site of protein synthesis
Cytoskeleton - 🧠ANSWER ✔✔A network of fibers that holds the cell
together, helps the cell to keep its shape, and aids in movement
-Prokaryotes have less extensive cytoskeleton
Cell wall - 🧠ANSWER ✔✔a fibrous layer found outside the plasma
membrane of most bacteria and archaea and eukaryotes
flagellum - 🧠ANSWER ✔✔A long, hairlike structure that grows out of a cell
and enables the cell to move.
