A researcher observes two different types of cells. Cell X contains only 70S ribosomes, whereas Cell Y contains both 70S and 80S ribosomes. Identify the correct statement regarding these cells.

Step-by-step solution

Cell X contains only 70S ribosomes, which indicates it is a prokaryotic cell. Prokaryotes lack a nuclear envelope and membrane-bound organelles such as mitochondria. Cell Y contains both 70S and 80S ribosomes, indicating it is a eukaryotic cell (80S ribosomes are found in the cytoplasm and 70S ribosomes are found inside semi-autonomous organelles like mitochondria or plastids). Eukaryotic cells possess an endomembrane system and other membrane-bound organelles, which are absent in prokaryotic cells. Their primary g
