Which one pair of examples will correctly represent the grouping Spermatophyta according to one of the schemes of classifying plants : -
A
Acacia, Sugarcane
B
Pinus, Cycas
C
Rhizopus, Triticum
D
Ginkgo, Pisum
The answer is D.
Solution
Spermatophyta (seed plants) includes two groups: gymnosperms (naked seeds) and angiosperms (seeds enclosed in fruits). A pair that correctly represents the whole grouping should include one member of each group. Ginkgo is a gymnosperm and Pisum (pea) is an angiosperm, so this pair represents both subdivisions of Spermatophyta. Acacia and sugarcane are both angiosperms; Pinus and Cycas are both gymnosperms; Rhizopus is a fungus and does not produce seeds. So the pair that correctly represents Spermatophyta is Ginkgo and Pisum.
