MCQs on Plant Kingdom

The plant kingdom consists of 390,000 species known till date. The plant kingdom is divided into five major groups:

  • Thallophyta
  • Bryophyta
  • Pteridophyta
  • Gymnosperms
  • Angiosperms

Given below are MCQs on the Plant Kingdom which will help you analyse your understanding on the topic. The answers are also provided for reference.

  1. Can u clarify why bryophytes are the first plants to inhabit land??

    1. Molecular phylogenetic studies proved that bryophytes are the earliest diverging lineages of the extant land plants.

    2. They are known as amphibians of the plant kingdom.

    3. bryophytes are non vascular,archegoniate,embryophytic and first land plants

    4. From the point of view of their evolution the Bryophytes stand at level higher than that of Thallophytes but lower than that of Pteridophytes and Phanerogams. The plants belonging to Algae are commonly found in water and rarely on the land, whereas the Bryophytes are land inhabiting plants. The water is still needed for the movement of the gametes of Bryophtes and in their vegetative structure they have adapted themselves to a terrestrial life. The Bryophytes are known as amphibians of the plant kingdom.
