| List – I | List – II |
|---|---|
| (A) Autogamy | (I) Oxalis |
| (B) Chasmogamous flower | (II) Pollination within same flower |
| (C) Geitonogamy | (III) Genetically different types of pollens fall on stigma of the flower |
| (D) Xenogamy | (IV) Transfer of pollen grains from the anther to the stigma of another flower of same plant |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
(A) Autogamy — this matches (II) Pollination within same flower.
(B) Chasmogamous flower — this matches (I) Oxalis. Oxalis has both chasmogamous and cleistogamous flowers.
(C) Geitonogamy — this matches (IV) Transfer of pollen grains from the anther to the stigma of another flower of same plant.
(D) Xenogamy — this matches (III) Genetically different types of pollens fall on stigma of the flower.
NCERT Extract:
Pollination – “… (i) Autogamy : In this type, pollination is achieved within the same flower.”
Pollination – “… (ii) Geitonogamy – Transfer of pollen grains from the anther to the stigma of another flower of the same plant.”
Pollination – “… Some plants such as Viola (common pansy), Oxalis, and Commelina produce two types of flowers – chasmogamous flowers which are similar to flowers of other species with exposed anthers and stigma, and cleistogamous flowers which do not open at all (Figure 1.9c).”
