Multiple Choice

Non-membranous organelles are not isolated from the cytosol.

Explanation:
Non-membranous organelles are not isolated from the cytosol because they lack a surrounding lipid membrane. Without a barrier, these structures—such as ribosomes, proteasomes, and components of the cytoskeleton—reside directly in the cytosol and can exchange molecules, ions, and information with the cytosolic environment immediately. This contrasts with membranous organelles (like mitochondria, ER, Golgi, lysosomes, and the nucleus), whose membranes create separate internal compartments and regulate what enters or leaves. So the lack of a membrane means they remain in direct contact with the cytosol, making the statement true.
