Q1.Given below are two statements: In the light of the above statements, choose the most appropriate answer from the options given below:

  • Statement I: In gymnosperms, the male and female gametophytes remain within the sporangia.
  • Statement II: In gymnosperms, seeds are not covered.
  • ABoth Statement I and Statement II are correctAnswer
  • BBoth Statement I and Statement II are incorrect
  • CStatement I is correct but Statement II is incorrect
  • DStatement I is incorrect but Statement II is correct

Explanation

Gymnosperm gametophytes are heavily reduced and never live independently — they stay inside the sporangia on the parent sporophyte. And the name itself says the rest: gymnosperm means naked seed, because the ovules sit exposed with no ovary wall around them before or after fertilisation.

Q3.Given below are the stages in the life cycle of pteridophytes. Arrange the following stages in the correct sequence.

  • A. Prothallus stage
  • B. Meiosis in spore mother cells
  • C. Fertilisation
  • D. Formation of archegonia and antheridia in gametophyte
  • E. Transfer of antherozoids to the archegonia in presence of water
  • AB, A, D, E, CAnswer
  • BB, A, E, C, D
  • CD, E, C, A, B
  • DE, D, C, B, A

Explanation

Start from the dominant sporophyte. Spore mother cells in the sporangium undergo meiosis to give haploid spores, which germinate into the prothallus, the free living gametophyte. The prothallus then bears antheridia and archegonia, antherozoids swim through a film of water to the archegonium, and fertilisation restores the diploid sporophyte. The sequence is B, A, D, E, C.
