Question

When pollen is transferred from the anther of one flower to the stigma of another flower of the same plant, pollination is referred to:

a)
Geitonogamy
b)
Allogamy
c)
Xenogamy
d)
Siphonogamy

Correct answer is option 'A'. Can you explain this answer?

Answer

Option A is correct.. geitonogamy means when pollen grain is transferred from anther of flower to stigma of another flower of the same plant.. hence it is genetically self pollination and ecologycally cross pollination..

Answer

Answer

Geitonogamy refers to the transfer of pollen from the anther of one flower to the stigma of another flower of the same plant. This process occurs when the pollen is transferred between flowers on the same individual plant.

Explanation:

Geitonogamy is a type of self-pollination, which means that the pollen and stigma involved in pollination belong to the same plant. In geitonogamy, the pollen grains are transferred from the anther to the stigma of another flower on the same plant, either by wind or insects.

Geitonogamy can occur in plants that have both male and female reproductive organs in the same flower, such as tomatoes, or in plants that have separate male and female flowers on the same plant, such as squash.

Advantages of Geitonogamy:

1. It increases the chances of successful reproduction because the pollen is guaranteed to be genetically compatible with the flower it is being transferred to.

2. It ensures the continuation of desirable traits within a population of plants.

3. It allows for reproduction even in the absence of cross-pollinators like bees and other insects.

Disadvantages of Geitonogamy:

1. It can lead to inbreeding, which can reduce genetic diversity and lead to the accumulation of harmful mutations.

2. It can reduce the chances of successful fertilization if the pollen transferred is not viable or if the stigma is not receptive at the time of pollination.

In conclusion, geitonogamy is an important process of pollination in plants that ensures successful reproduction even in the absence of cross-pollinators. However, it is important to maintain genetic diversity in plant populations to avoid the accumulation of harmful mutations.

Answer

Yes it's geitonogamy transfer of pollen from anther to stigma of same flower is known as autogamy and transfer of pollen from anther to stigma of another flower from same plant is known as geitonogamy and transfer of pollen grains from anther to the stigma of different plant is known as xenogamy

Answer

It is clearly mentioned in ncert ,refer the 12 class ncert  biology  book

Answer

In self-pollinating plants, there is less dependence on the external factors to cause pollination. These plants depend on wind or other smaller insects that visit the flower regularly. In self- pollinating flowers, the anthers, and stigma are of similar lengths to facilitate the transfer of pollen. Self -pollination can be further divided into two types:

Autogamy– In this type of self-pollination, the pollen is transferred from the anthers of one flower to the stigma of the same flower.
Geitonogamy– In this type of self- pollination, the anthers are transferred from the anthers of one flower to the stigma of another flower but on the same plant.
