Read the following five statements and answer the question.
$(a)$ In equisetum the female gametophyte is retained on the parent sporophyte.
$(b)$ In Ginkgo male gametophyte is not independent.
$(c)$ The sporophyte in Riccia is more developed than that in Polytrichum.
$(d)$ Sexual reproduction in Volvox is isogamous.
$(e)$ The spores of slime molds lack cell walls.
How many of the above statement are correct?
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
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 |
Choose the correct answer from the options given below:
Draw labelled diagrams of
$(a)$ Female and male thallus of a liverwort.
