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:
$(a) - (ii), (b) - (iii), (c) - (iv), (d) - (i)$
$(a) - (iii), (b) - (iv), (c) - (i), (d) - (ii)$
$(a) - (ii), (b) - (iv), (c) - (i), (d) - (iii)$
$(a) - (iv), (b) - (i), (c) - (ii), (d) - (iii)$
When and where does reduction division take place in the life cycle of a liverwort, a moss, a fern, a gymnosperm and an angiosperm?
Differentiate between the following:
$(i)$ red algae and brown algae
$(ii)$ liverworts and moss
$(iii)$ homosporous and heterosporous pteridophyte
$(iv)$ syngamy and triple fusion
Which of the following is grouped under phanerogams
Read the following statements and answer the question which follows them
$(1)$ In liverworts, mosses and ferns gametophytes are free-living
$(2)$ 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?
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
