difference between geitonogamy and cleistogamous?
Answers
Answer:
Geitonogamy is the transfer of pollen from the anther of one flower to the stigma of another flower on the same plant. Xenogamy is the transfer of pollen from the anther of one flower of a plant to the stigma of another flower of a different plant.
Answer:
Geitonogamous flowers are the flowers in which pollen are transferred from the anther to the stigma of other flower on the same plant. These flowers also need external agencies for pollination.
Cleistogamy is the phenomenon, where flowers never open and in such flowers, only self-pollination occurs within the bud (unopened flower). Bisexual flowers which do not open at all are called cleistogamous. In such flowers, anthers and stigma lie close to each other. When the anthers dehisce in the flower buds, pollen grains come in contact with the stigma and pollination occurs. Cleistogamous flowers are not dependent on external agencies for pollination. Hence, seed setting is not dependent on pollinators.
