Androphore structure is formed by :a)Internodeb)Nodec)Sepalsd)PetalsCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Androphore : It is the second elongated internode between corolla and androecium, e.g., Gynandropsis. ... Carpophore : This is a stalk like connection present between two carpels. It is formed due to expansion of the thalamus between the carpels, e.g., Coriandrum and Foeniculum.

Answer

According to goethe flower is a modified shoot. if the length of internode between the Corolla and androecium increases then it is called androphore.

Answer

Androphore structure is formed by:
The androphore structure is formed by the internode.
Explanation:
The androphore structure refers to the modified stem in certain flowers where the stamens are attached. Here is a detailed explanation of how the androphore structure is formed by the internode:
- Internode: The internode is the section of the stem between two adjacent nodes. In the case of the androphore structure, it is the internode that undergoes modification to form the androphore.
- Modification: During the development of the flower, the internode between the receptacle and the stamens elongates and becomes specialized to hold the stamens in a higher position.
- Attachment: The stamens, which are the male reproductive organs of the flower, are attached to the androphore. They are typically fused to the androphore or attached near its base.
- Support: The androphore provides support to the stamens, elevating them to a higher position within the flower. This positioning can be crucial for efficient pollination.
- Function: The androphore structure allows the stamens to be positioned closer to the center of the flower, where they can easily release pollen onto the pistil, enhancing the chances of successful pollination and fertilization.
In conclusion, the androphore structure is formed by the internode, which undergoes modification to provide support and proper positioning for the stamens in certain flowers.
