Strasburger is famous for

Match List $- I$ with List $- II.$

List $- I$	List $- II$
$A$. Centromere	$I$. Mitochondrion
$B$. Cilium	$II$. Cell division
$C$. Cristae	$III$. Cell movement
$D$. Cell membrane	$IV$. Phospholipid Bilayer

Choose the correct answer from the options given below:

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?

Select the correct match for $X$ and $Y$:

Column $X$	Column $Y$
$(1)$ Vacuole	$(P)$ Absent in human erythrocytes
$(2)$ Nucleus	$(Q)$ Perinuclear space absent
$(3)$ Nuclear envelope	$(R)$ Synthesis of $rRNA$
$(4)$ Nucleolus	$(S)$ Maintains turgor pressure in cells

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

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
