BIOXII02: SEXUAL REPRODUCTION IN FLOWERING PLANTS
341670
The type of out breeding device, the flowers are structurally bisexual and functionally unisexual is
1 Herkogamy
2 Heterostylly
3 Dichogamy
4 Monogamy
Explanation:
Dichogamy is further divided into protogyny - stigma becomes receptive first and protoandry- anther becomes receptive first.
BIOXII02: SEXUAL REPRODUCTION IN FLOWERING PLANTS
341671
Stigmas mature earlier so that they get pollinated before the anthers of the same flower develop pollen grains.
1 Herkogamy
2 Protogyny
3 Self incompatibility
4 Unisexuality
Explanation:
Protogyny - Stigmas mature earlier so that they get pollinated before the anthers of the same flower develop pollen grains.
BIOXII02: SEXUAL REPRODUCTION IN FLOWERING PLANTS
341672
A genetic mechanism to prevent self-pollen by inhibiting pollen germination or pollen tube growth in the pistil
1 Self compatibility
2 Protogyny
3 Self incompatibility
4 Unisexuality
Explanation:
Another device to prevent inbreeding is self-incompatibility. This is a genetic mechanism and prevents self-pollen (from the same flower or other flowers of the same plant) from fertilising the ovules by inhibiting pollen germination or pollen tube growth in the pistil.
BIOXII02: SEXUAL REPRODUCTION IN FLOWERING PLANTS
341673
Autogamy and geitonogamy is absent in
1 Date palm
2 Maize
3 Castor
4 All are correct
Explanation:
In several species such as datepalm, male and female flowers are present on different plants, that is each plant is either male or female (dioecy). This condition prevents both autogamy and geitonogamy.
