$A$ bacterial cell divides every minute. It takes one hour to fill up a cup. How much time will it take to fill half the cup?

In $Ophioglossum$ (a fern),the chromosome number in a gamete is ..... and in potato,the chromosome number in a gamete is ....

In bacteria,fungi,and lower plants,various thick-walled $A$ are formed,which help them to survive $B$ conditions; these germinate on the availability of a suitable environment. In higher plants,$C$ and some other vegetative reproductive structures serve as means to tide over periods of stress besides helping in dispersal; they germinate to form new plants under favourable moisture and temperature conditions. Choose the correct option for $A, B$,and $C$.

Match List-$I$ with List-$II$:

List-$I$	List-$II$
$a$. Chlamydomonas	$i$. Conidia
$b$. Penicillium	$ii$. Zoospores
$c$. Hydra	$iii$. Gemmules
$d$. Sponge	$iv$. Buds

Choose the correct answer from the options given below:

Differentiate between asexual reproduction and sexual reproduction.

Match the following columns:

List-$I$	List-$II$
$(a)$ Primates	$(1)$ Fusion of gametes
$(b)$ Non-primates	$(2)$ Continuous breeders
$(c)$ Fertilization	$(3)$ Growth phase
$(d)$ Juvenile phase	$(4)$ Seasonal breeders
