Vedclass · Answer

(C) $1$. Centrioles are involved in spindle formation during cell division,not $RNA$ synthesis. $RNA$ synthesis occurs in the nucleolus.$2$. Lysosomes contain hydrolytic enzymes that are optimally active at acidic $pH$ (around $5.0$),not $8.5$.$3$. Thylakoids are flattened,sac-like structures found inside chloroplasts. Stacks of thylakoids are called grana. This statement is correct.$4$. Ribosomes in the cytoplasm of eukaryotic cells are $80S$,while those in chloroplasts and mitochondria are $70S$. The statement provided is reversed.

Column $I$	Column $II$
$A$. Centrioles	$I$. Non-membrane bound organelle which helps in cell division
$B$. Fimbriae	$II$. Special structure of bacteria which help them to attach to rocks in streams
$C$. Endomembrane system	$III$. Includes those organelles whose functions are coordinated
$D$. Mitochondria	$IV$. Divide by fission and site of aerobic respiration
