Which of the following structures is formed by the collective functioning of all membranous organelles in terms of their structure and function?

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

Eukaryotic cells have a well-organized nucleus and:
$a$. Both $70S$ and $80S$ types of ribosomes
$b$. Flagella associated with $9+2$ organization
$c$. Shows cytoplasmic streaming
$d$. Their $DNA$ is complexed with histones to constitute the chromatin

Differentiate between a plant cell and an animal cell.

Which group of organelles is not part of the endomembrane system?

Column-$I$ represents the organelle and Column-$II$ represents its structure. Select the correct option:

Column-$I$	Column-$II$
$(A)$ Mitochondria	$(i)$ Single membrane-bound structure
$(B)$ Lysosome	$(ii)$ Non-membrane-bound structure
$(C)$ Nucleolus	$(iii)$ Double membrane-bound structure
