Q. Herkogamy favours cross pollination. In Pansy there is a hood covering the stigma. So how can pollen from other plants reach this stigma?

Q. Classify the given statements under the headings 'self pollination ' and 'cross pollination'.
a. Transfer of pollen grains from the anther to the stigma of the same flower.
b. Transfer of pollen grains from the anther to the stigma of a different flower.
c. No need of pollinators to transfer pollen grains.
d. Produces large amounts of pollen grains.
e. Requires pollinators to transfer pollen grains.

1. Self pollination- a, c
   Cross pollination- b, d, e
2. Self pollination- a, d
   Cross pollination- b, c, e
3. Self pollination- b, d, e
   Cross pollination- a, c
4. Self pollination- a, c, e
   Cross pollination- b, d

Q. Choose the correct statement with respect to cross pollination.

1. Transfer of pollen grains from anther of one flower to the stigma of the another flower on the same plant.
2. Transfer of pollen grains from anther of one flower to the stigma of another flower present on a different plant of the same species.
3. Transfer of pollen grains from anther of one flower to the stigma of the same flower.
4. Transfer of pollen grains from anther of one flower to the stigma of another flower present on a different plant of different species.

Q. Choose the correct statement(s) with respect to self pollination.

1. Transfer of pollen from anther of one flower to the stigma of the same flower.
2. Transfer of pollen from anther of one flower to the stigma of another flower present on the different plant of the same species.
3. Transfer of pollen from anther of one flower to the stigma of the another flower on the same plant.
4. Transfer of pollen from anther of one flower to the stigma of another flower present on the different plant of the different species.
