Ques. 1AIPMT 2003
Which one pair of examples will correctly represent the grouping spermatophyta according to one of the schemes of classifying plants?
- Acacia, sugarcane
- Pinus, Cycas
- Rhizopus, Triticum
- Ginkgo, Pisum
Answer
(4) Ginkgo, Pisum
Solution
Spermatophyta (seed plants) includes both gymnosperms and angiosperms.
⇒ A pair that represents the whole grouping must contain one gymnosperm and one angiosperm.
⇒ Ginkgo is a gymnosperm and Pisum (pea) is an angiosperm.
∵ Acacia and sugarcane are both angiosperms; Pinus and Cycas are both gymnosperms; Rhizopus is a fungus.
∴ Ginkgo and Pisum correctly represent spermatophyta.
