Question

A membrane covering is lacking around
(A) Lysosome (B) Nucleolus
(C) Mitochondria
(D) Plastid

Answer 1

Answer:

Nuclelus

Explanation:

The nucleolus is a small, dense and spherical structure present in the nucleus of the cell which lacks a membrane and is visible during the interphase of the cell division under the microscope.

This region is dense due to the presence of proteins, DNA and RNA which are formed from specific chromosomal regions called nucleolar organizing regions. 

Lysosome, mitochondria and plastids are membraned cell organelles present within a cell.

So, the correct answer is 'Nucleolus'.

Answer 2

The membrane covering is lacking around NUCLEOLUS.

Also centriole and ribosome lack membranous covering.
