Detailed explanation-1: -Thus, the correct answer is ‘Mitochondria.

Detailed explanation-2: -In eukaryotes, vertebrates don’t have a cell wall but plants do. The cell walls of prokaryotes differ chemically from the eukaryotic cell walls of plant cells, which are primarily made of cellulose.

Detailed explanation-3: -Cell walls are found in both prokaryotes and eukaryotes, although not all cells have cell walls. In Figure 1, the diagram of a plant cell, you see a structure external to the plasma membrane which is the cell wall.

Detailed explanation-4: -Ribosomes are the cell organelles that are not surrounded by a membrane. Nucleus, mitochondria and lysosomes are surrounded by membranes.

Detailed explanation-5: -Explanation: Unlike eukaryotes, prokaryotes have no membrane-bound organelles. This means that they lack a nucleus, mitochondria, and other advanced cell structures.
