Question

Some cellular structures are bound by single or double membranes while some others are without a membrane.

Match the organdies in List-I with the nature of membranes in List-II and select the correct answer using the codes given the lists.

List-I	List-II
a. Mitochondria	$1$. Without membrane
b. Lysosomes	$2$. Single membrane
c. Ribosomes	$3$. Double membrane
d. Nucleus	$4$. Triple membrane

• A. A-$1$, B-$2$, C-$3$, D-$2$
• B. A-$3$, B-$1$, C-$2$, D-$1$
• C. A-$3$, B-$2$, C-$1$, D-$3$
• D. A-$2$, B-$3$, C-$1$, D-$3$

Answer 1

The correct option is C A-$3$, B-$2$, C-$1$, D-$3$

The cellular components are called cell organelles. These cell organelles include both membrane and non-membrane bound organelles, present within the cells and are distinct in their structures and functions. They coordinate and function efficiently for the normal functioning of the cell. A few of them function by providing shape and support, whereas some are involved in the locomotion and reproduction of a cell. There are various organelles present within the cell and are classified into three categories based on the presence or absence of membrane.

Organelles without membrane: The Cell wall, Ribosomes, and Cytoskeleton are non-membrane-bound cell organelles. They are present both in prokaryotic cell and the eukaryotic cell.

Single membrane-bound organelles: Vacuole, Lysosome, Golgi Apparatus, Endoplasmic Reticulum are single membrane-bound organelles present only in a eukaryotic cell.

Double membrane-bound organelles: Nucleus, mitochondria and chloroplast are double membrane-bound organelles present only in a eukaryotic cell.

So, the correct option is 'C'.
