Find the odd one out.
Vacuoles, Nucleus, Ribosomes, Lysosomes
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Ribosomes.
The odd one out is Ribosomes because they are not membrane-bound organelles, while the others are. Vacuoles, Nucleus, and Lysosomes are all enclosed by membranes and are considered membrane-bound organelles found mainly in eukaryotic cells. Ribosomes, on the other hand, are non-membranous structures made of RNA and proteins and are present in both prokaryotic and eukaryotic cells. They are primarily responsible for protein synthesis and can be found either floating freely in the cytoplasm or attached to the rough endoplasmic reticulum.
