In eubacteria, a cellular component that resembles eukaryotic cell is:

Explanation

Plasma membrane of eubacteria resembles plasma membrane of eukaryotic cell. But nucleus, ribosomes and cell wall are little different in eukaryotic cell in their structure and organization from eubacterial cell. Plasma Membrane: The plasma membrane, also known as the cell membrane, is a structure shared by both eubacteria (prokaryotes) and eukaryotic cells. It serves as a selective barrier that controls the passage of substances in and out of the cell, just like in eukaryotic cells. Nucleus: Eubacteria do not possess a true nucleus. Unlike eukaryotic cells, which have a distinct membrane-bound nucleus housing their genetic material, eubacteria have a nucleoid region where their DNA is located, but it lacks a membrane. Ribosomes: Ribosomes are cellular structures responsible for protein synthesis. Both eubacteria and eukaryotic cells have ribosomes, but there can be some differences in their ribosome structure and organization. Cell Wall: Eubacteria typically have a cell wall, which is a rigid outer layer providing structural support and protection to the cell. This is a feature shared with some eukaryotic cells, such as plant cells and fungi, but not all eukaryotic cells have cell walls.
