Vedclass · Answer

(D) In eukaryotic cells,most organelles are membrane-bound. However,some organelles lack a membrane. $1$. $Ribosomes$: These are protein-synthesizing machineries made of $RNA$ and proteins,and they are not enclosed by any membrane. $2$. $Nucleolus$: This is a dense,spherical structure present inside the nucleus where ribosomal $RNA$ is synthesized; it is also membrane-less. $3$. $Centrosome$: This is an organelle involved in cell division,consisting of two centrioles surrounded by amorphous pericentriolar material,and it lacks a membrane. Therefore,$Ribosomes$,$Nucleolus$,and $Centrosome$ are membrane-less organelles.
