Difference Between Geitonogamy and Xenogamy

Difference Between Geitonogamy and Xenogamy

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.

Is Xenogamy and Allogamy same?

The main difference between allogamy and xenogamy is that allogamy is the deposition of pollen grains from the anther of the one flower on the stigma of another flower, either in the same plant or a in a different plant of the same species whereas xenogamy is the deposition of pollen grains from the anther of one ...

What is the difference between Autogamy and Geitonogamy?

Autogamy refers to the transfer of pollen grains from the anther to the stigma of the same flower, whereas geitonogamy refers to the transfer of pollen grains from the anther to the stigma of another flower of the same plant.

What does Xenogamy mean?

Xenogamy (Greek xenos=stranger, gamos=marriage) is the transfer of pollen grains from the anther to the stigma of a different plant. ... Cross-pollination involves the transfer of pollen grains from the flower of one plant to the stigma of the flower of another plant.

What is Autogamy and Xenogamy?

Autogamy is self pollination, that is pollination of the ovules of a flower by its own pollen. Xenogamy is pollination of the stigma of a flower by pollen from a flower on another plant.

Is Papaya a Xenogamy?

Hint: Xenogamy is the type of pollination where the transfer of pollen from one flower takes place to the stigma of the flower of another plant. ...

What is self incompatibility?

Self-incompatibility is a widespread mechanism in flowering plants that prevents inbreeding and promotes outcrossing. The self-incompatibility response is genetically controlled by one or more multi-allelic loci, and relies on a series of complex cellular interactions between the self-incompatible pollen and pistil.

Why is complete Autogamy rare?

Complete autogamy is rare in chasmogamous flower. Perfect synchronization between pollen release and stigma receptivity is required in such flowers to allow self-pollination. Cleistogamous Flower: When a flower does not open at all and thus does not expose its anthers and stigma, it is called cleistogamous flower.

What are the advantages of Geitonogamy?

If a plant is self-incompatible, geitonogamy can reduce seed production. Geitonogamy is when pollen is exported using a vector (pollinator or wind) out of one flower but only to another flower on the same plant. It is a form of self-fertilization.

What is Xenogamy and give example?

Xenogamy is a cross pollination in which pollen grain from anther of one flower to the stigma of another flower are transferred in order to get fertilised. Explanation: ... Example of xenogamy involves: Squash, onions, broccoli, and spinach.

What is Anaemophily?

Anemophily is a type of pollination in which the pollens are carried by the wind. Here wind acts as pollinating agent. Most of the gymnosperms, grasses, oak etc. are anemophilous plants.

How many of the following plants show Xenogamy only?

Papaya is a unisexual plant in which male and female flowers are present on different plants. Hence, the plant can exhibit xenogamy only.
