Which of the following organelles is single-membrane bound?

Which of the following is an endomembrane system component?

Match the following columns correctly.

Column-$I$	Column-$II$
$(a)$ Membrane-bound organelle	$(p)$ Ribosomes
$(b)$ Non-membrane-bound organelle	$(q)$ Mitochondria
$(c)$ Largest cell	$(r)$ Mycoplasma
$(d)$ Smallest cell	$(s)$ Ostrich egg

Mitochondria and chloroplasts:
$(a)$ Are semi-autonomous organelles.
$(b)$ Are formed by the division of pre-existing organelles. They contain $DNA$,but lack protein-synthesizing machinery.
Which of the following options is correct?

Match the column $I$ with column $II$.

Column-$I$	Column-$II$
$(a)$. Glyoxysome	$(i)$. Plant lysosomes
$(b)$. Sphaerosome	$(ii)$. Glyoxylate cycle
$(c)$. Mitochondria	$(iii)$. Photorespiration
$(d)$. Peroxisome	$(iv)$. Succinate dehydrogenase

Match Column $I$ with Column $II$ and choose the correct option.

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
