A
Mitochondrion
B
Ribosome
C
Nucleus
D
Endoplasmic reticulum
Verified step by step guidance1
Identify the key characteristic of prokaryotic cells: Prokaryotic cells lack membrane-bound organelles, which is a defining feature of their structure.
Review the options provided: Mitochondrion, Ribosome, Nucleus, and Endoplasmic Reticulum. Determine which of these structures are membrane-bound.
Understand that mitochondria, the nucleus, and the endoplasmic reticulum are all membrane-bound organelles, which are absent in prokaryotic cells.
Recognize that ribosomes are non-membranous structures responsible for protein synthesis and are present in both prokaryotic and eukaryotic cells.
Conclude that the correct answer is 'Ribosome,' as it is the only structure listed that lacks a membrane and is found in prokaryotic cells.
