The kingdom Plantae as laid down by R. Whittaker comprises which of the following group of plants ?

Result
Your answer: —  Â·  Correct: D

Explanation

Robert Whittaker's Five Kingdom Classification (1969) categorized living organisms into Monera, Protista, Fungi, Plantae, and Animalia. Kingdom Plantae consists of multicellular, eukaryotic, and autotrophic organisms. It is further subdivided into five major groups:

  • Thallophyta: Simple plants like algae.
  • Bryophyta: Non-vascular plants like mosses.
  • Pteridophyta: Vascular plants like ferns.
  • Gymnosperms: Plants with naked seeds.
  • Angiosperms: Flowering plants with enclosed seeds.

Options A, B, and C are incorrect because they include Monera, Protista, or Fungi, which Whittaker established as distinct kingdoms separate from Kingdom Plantae.
