Consider the following four statements whether they are correct or wrong.
$A.$ The sporophyte in liverworts is more elaborate than that in mosses.
$B.$ Salvinia is heterosporous.
$C.$ The lifecycle in all seedbearing plants is diplontic.
$D.$ In Pinus male and female cones are borne on different trees.The two wrong statements together are
$A$ and $C$
$A$ and $D$
$B$ and $C$
$A$ and $B$
Identify correct pair :
$\begin{array}{|l|l|} \hline Column\,\,-\,\,I & Column\,\,-\,\,II \\ \hline (1)\,\,Gymnosperm & (p)\,\,Sphegnum \\ \hline (2)\,\,Angiosperml & (q)\,\,Sellaginella \\ \hline (3)\,\,Bryophytes & (r)\,\,Pinus \\ \hline (4)\,\,Pteridophyte & (s)\,\,Eucalyptus \\ \hline \end{array}$
Read the following statements and answer the question which follows them

$(2)$ Gymnosperms and some ferns are heterosporous
$(3)$ Sexual reproduction in Fucus, Volvoxand albugo is oogamous
$(4)$ The sporophyte in liveworts is more elaborate than that in mosses
$(5)$ Both Pinus and Marchantia aredioecious
How many of the above statements are correct?
Match List$- I$ with List $- II$ :
List$- I$ | List $- II$ |
$a$ Chlamydomonas | $i$ Moss |
$b$ Cycas | $ii$ Pteridophyte |
$c$ Selaginella | $iii$ Alga |
$d$ Sphagnum | $iv$ Gymnosperm |
Choose the correct answer from the options given below :
Draw labelled diagrams of
$(a)$ Female and male thallus of a liverwort.
$(b)$ Gametophyte and sporophyte of funaria.
$(c)$ Alternation of generation in angiosperm.
Match the plant with the kind of life cycle it exhibits:
$List-I$ | $List - II$ |
$(a)$ Spirogyra | $(i)$ Dominant diploid sporophyte vascular plant, with highly reduced male or female gametophyte |
$(b)$ Fern | $(ii)$ Dominant haploid free-living gametophyte |
$(c)$ Funaria | $(iii)$ Dominant diploid sporophyte alternating with reduced gametophyte called prothallus |
$(d)$ Cycas | $(iv)$ Dominant haploid leafy gametophyte alternating with partially dependent |
