What is the jelly-like substance inside bacterial cells that fills the interior of the cell?

• A. Ribosome
• B. Capsule
• C. Cytoplasm
• D. Nucleus

Answer: (C)

In bacterial cells, the jelly-like interior is the cytoplasm. This gel-like substance is mostly cytosol—the watery fluid with dissolved nutrients and enzymes—where many metabolic activities take place. The cytoplasm also houses ribosomes, the tiny machines that build proteins, and the nucleoid region where the cell’s DNA is located. Capsule refers to a protective layer that some bacteria have outside the cell wall, and bacteria do not have a true nucleus. So the interior filling substance is cytoplasm.
