$S$ - Statement: Mitochondria are associated with the process of respiration.
$R$ - Reason: Chloroplasts are associated with the process of photosynthesis.

Which of the following statements are correct?
$(i)$ In prokaryotic cells,a special membranous structure formed by the extension of the plasma membrane into the cell is known as polysome.
$(ii)$ The smooth endoplasmic reticulum is the major site for synthesis of glycoproteins.
$(iii)$ $RuBisCO$ is the most abundant protein in the whole biosphere.
$(iv)$ Mitochondria,chloroplasts,and peroxisomes are not considered as part of the endomembrane system.

Match List $I$ with List $II$:

List $I$	List $II$
$A$. Nucleolus	$I$. Site of formation of glycolipid
$B$. Centriole	$II$. Organization like the cartwheel
$C$. Golgi apparatus	$III$. Site for active ribosomal $RNA$ synthesis
$D$. Leucoplast	$IV$. For storing nutrients

Choose the correct answer from the options given below:

The process by which large molecules move out of the cell is called

Write the functions of the following:
$(a)$ Centromere
$(b)$ Cell wall
$(c)$ Smooth $ER$
$(d)$ Golgi apparatus
$(e)$ Centrioles

$S$ - Statement: The nucleolus is the regulatory center for various activities occurring in the cell.
$R$ - Reason: Rudolf Virchow coined the term 'cell'.
