    Answer and solution

    Answer: (2)

    Naked ovules that are not enclosed within an ovary and remain exposed both before and after fertilisation are the defining feature of gymnosperms. Among the choices, Pinus is a gymnosperm (2). Funaria is a moss (bryophyte), Selaginella is a pteridophyte, and Wolffia is a flowering angiosperm whose ovules are enclosed in an ovary.

    Given below are two statements:

    Statement I: In gymnosperms, the male and female gametophytes remain within the sporangia.
    Statement II: In gymnosperms, seeds are not covered.

    In the light of the above statements, choose the most appropriate answer from the options given below:

    1. (1)

      Both Statement I and Statement II are correct

    2. (2)

      Both Statement I and Statement II are incorrect

    3. (3)

      Statement I is correct but Statement II is incorrect

    4. (4)

      Statement I is incorrect but Statement II is correct

    Answer and solution

    Answer: (1)

    Gymnosperms are heterosporous, and unlike in pteridophytes the gametophytes never become free-living: the reduced male gametophyte stays inside the pollen grain within the microsporangium, and the female gametophyte remains enclosed in the megasporangium (nucellus) on the ovule. The name itself, gymno meaning naked and sperma meaning seed, records the second fact - the ovules sit exposed on the megasporophyll with no ovary wall around them, so no fruit is formed. NCERT Class 11, Plant Kingdom.

  2. Re-NEET 2026 · Q121

    Pteridophytes are divided into four classes: Psilopsida, Lycopsida, Sphenopsida and Pteropsida. Sphenopsida contains the horsetails, chiefly Equisetum, recognised by jointed ridged stems bearing whorls of scale leaves. These are the first vascular land plants, with true xylem and phloem.
