Examine the figures A, B, C and D. In which one of the four options are all the items A, B, C and D correct?
A
A – $Chara$, B – $Marchantia$, C – $Fucus$, D – $Pinus$
B
A – $Equisetum$, B – $Ginkgo$, C – $Selaginella$, D – $Lycopodium$
C
A – $Selaginella$, B – $Equisetum$, C – $Salvinia$, D – $Ginkgo$
D
A – $Funaria$, B – $Adiantum$, C – $Salvinia$, D – $Riccia$
Detailed Solution
Figure A shows a creeping, branched plant with small scale-like leaves and roots arising from the stem: $Selaginella$ (a pteridophyte, the 'spike moss').
Figure B shows an erect, jointed stem with whorls of slender branches at the nodes and a terminal cone (strobilus): $Equisetum$ (horsetail).
Figure C shows a floating aquatic fern with rounded leaves above and root-like submerged leaves below: $Salvinia$.
Figure D shows a shoot with fan-shaped leaves: $Ginkgo$, a gymnosperm.
Hence A – $Selaginella$, B – $Equisetum$, C – $Salvinia$, D – $Ginkgo$.
