Question

Cross pollination in crop plant is known as

• A. Autogamy
• B. Allogamy
• C. Cleistogamy
• D. Chasmogamy

Answer 1

The correct option is B Allogamy

Cross pollination or allogamy is defined as fertilization of ovum of a flower by the pollen of another flower on the different plant. The pollen is transferred from the anther of the male flower to the stigma of the female flower. Allogamy takes place because of the male and female part of a particular flower mature at the different time. It can take place only when the flower is open. It is a source of recombination and can cause genetic variation.

So, the correct answer is option B.
