Sample questions

1. 1.Fusion between one large, non-motile female gamete and a smaller, motile male gamete is termed:

   • C.Oogamous
   • D.Heterogamous
2. 2.Why is the development of the seed habit considered an important step in evolution as discussed for heterosporous pteridophytes?
   • A.Because the zygote develops into a young embryo within the retained female gametophyte on the parent sporophyte
   • B.Because all spores become identical in size
   • C.Because the gametophyte becomes free-living
   • D.Because water is no longer required at any stage
3. 3.Assertion (A): The spread of living pteridophytes is limited to narrow geographical regions. Reason (R): Their gametophytes require cool, damp, shady places and water is needed for fertilisation.
   • A.Both A and R are true and R is the correct explanation of A
   • B.Both A and R are true but R is NOT the correct explanation of A
   • C.A is true but R is false
   • D.A is false but R is true

   • A.Both A and R are true and R is the correct explanation of A
   • B.Both A and R are true but R is NOT the correct explanation of A
   • C.A is true but R is false
