Geitonogamy is a functional cross pollination but not genetically. Justify?
(b) In Papaya, Autogamy and Geitonogamy do not occur. Give reason.

Both autogamy and geitonogamy cannot occur in

Geitonogamy is functionally similar to cross pollination and genetically similar to autogamy. Justify.

Assertion, Geitonogamy is functionally cross-pollination involving pollinating agent and genetically it is similar to autogamy since the pollen grains come from the another plant. Reason: Geitonogamy is the only type of pollination which during pollination brings genetically different types of pollen grains to the stigma.

When the pollen is transferred from anther to the stigma of same flower, the pollination is called autogamy. Geitonogamy is functionally cross pollination, but genetically similar to autogamy. Justify the statement.

What are cleistogamous flowers? Can cross-pollination occur in cleistogamo us flowers? Give reasons for you answer.
