  1. Question 1 · NEET 2026 · Q92 · +4 / −1

    In which one of the following, the ovules are not enclosed by an ovary wall and remain exposed?

    Answer and explanation

    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.

  2. Question 2 · Re-NEET 2026 · Q111 · +4 / −1

    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:

    Answer and explanation

    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.
