Which component is NOT part of the ultrastructure of eukaryotic cells?
Understand the Problem
The question is asking which of the listed components is not a part of the ultrastructure of eukaryotic cells. To answer it, we need to identify the components that are typically found in eukaryotic cells.
Answer
Ribosomes are not part of the ultrastructure of eukaryotic cells.
Ribosomes are not a membrane-bound organelle and could be considered as not part of the ultrastructure of eukaryotic cells.
Answer for screen readers
Ribosomes are not a membrane-bound organelle and could be considered as not part of the ultrastructure of eukaryotic cells.
More Information
Ultrastructure in eukaryotic cells typically refers to the complex network of membrane-bound organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, etc. Ribosomes, while being crucial for protein synthesis, are not membrane-bound.
Tips
A common mistake is assuming all organelles in a cell are part of its ultrastructure. However, ultrastructure often includes only membrane-bound organelles.
