Answer for Class 12 Biology Students

Out breeding Devices:

 In bisexual flowers, pollen grains are likely to come in contact with stigma of the same flower. Continued self-pollination results in in- breeding depression.

 Flowering plants have evolved devices to discourage self-pollination and to encourage cross- pollination, such devices are called out- breeding devices.

 Strategy 1: Anther and stigma are placed at different positions so that pollens cannot come in contact with stigma of the same flower.

 Strategy 2: Production of unisexual flowers.

 Strategy 3: In some species, anther release and stigma receptivity are not synchronized.

 Strategy 4: Self-incompatibility is a genetic mechanism which prevents self-pollen from fertilizing the ovule by inhibiting pollen germination on stigma.
