Question 8 please help

bacterial cell

Explanation:

In general, prokaryotic cells (bacterial cells) are smaller and less complex than eukaryotic cells. They lack membrane-bound organelles (such as mitochondria) and contain a nucleoid region instead of a membrane-bound nucleus. They do have ribosomes, but those are small (70S) and composed of one 30S and one 50S subunit.
