Insect pollinated flowers are cross pollinated ,as they are meant for that.
and okra has bisexual flower hence self pollinated.
In the following question, a Statement of Assertion (A) is given follo...
Assertion (A): All insect pollinated flowers are cross pollinated.
Reason (R): Okra is a self-pollinated plant.
Explanation:
Insect pollination is a method of pollination where insects, such as bees, butterflies, or moths, transfer pollen from the male reproductive organ (anther) of a flower to the female reproductive organ (stigma) of another flower. This process leads to fertilization and the production of seeds.
1. Insect Pollinated Flowers:
Insect pollinated flowers have certain characteristics that make them attractive and accessible to insects. These characteristics include brightly colored petals, a strong fragrance, and the production of nectar. Insects are attracted to these flowers and visit them in search of nectar as a food source.
2. Cross Pollination:
Cross pollination is a type of pollination where pollen from one plant is transferred to the stigma of a different plant of the same species. This can occur through various agents, including insects, wind, or water. In the case of insect pollination, insects inadvertently carry pollen from one flower to another as they move from flower to flower in search of nectar.
3. Assertion (A) - All insect pollinated flowers are cross pollinated:
The assertion that all insect pollinated flowers are cross pollinated is true. Insects play a crucial role in transferring pollen between flowers, and this process usually involves the transfer of pollen from one plant to another, leading to cross pollination. The characteristics of insect pollinated flowers, such as their attractive appearance and production of nectar, are specifically adapted to attract insects and facilitate cross pollination.
4. Reason (R) - Okra is a self-pollinated plant:
The reason that Okra is a self-pollinated plant is also true. Self-pollination occurs when pollen from the anther of a flower is transferred to the stigma of the same flower or another flower on the same plant. Okra has a unique flower structure that allows it to self-pollinate. The pollen is transferred within the same flower, without the need for external agents like insects or wind.
5. Correct Answer:
The correct answer is option 'B' - Both Assertion and Reason are true but Reason is not the correct explanation of Assertion. While both the assertion and reason are true, Okra being a self-pollinated plant does not provide a direct explanation for the assertion that all insect pollinated flowers are cross pollinated. The assertion is a general statement about insect pollinated flowers, while the reason specifically refers to Okra as an example of self-pollination.
