Answer: Pinus.
- A Mango
- B Pinus
- C Fern
- D Moss
Correct answer: B. Pinus
Explanation: Pinus (pine tree) is a gymnosperm with naked seeds in cones. Other examples include Cycas, Ginkgo, and Cedrus. Mango is an angiosperm, fern is a pteridophyte.
Plants evolved from water-dependent algae through increasingly land-adapted groups, gaining vascular tissue (Pteridophyta), then seeds (Gymnosperms), and finally fruit-enclosed seeds (Angiosperms) - each step reducing dependence on water for reproduction.
Concept context
Classification of plants from algae to angiosperms. Understanding plant diversity is essential for NEET.
