Final answer:
Connation in flowers refers to the fusion of like parts, and an example of this is when stamens fuse with petals, which are parts of the corolla that attract pollinators.
Step-by-step explanation:
An example of connation is the union of stamens, which are the male reproductive structures of a flower, with another floral part. Connation refers to the fusion of like parts, such as stamens fusing with other stamens or with petals. The stamens consist of a stamen and an anther, where the pollen grains develop. Stamens can form connections with petals, indicating that the correct answer to the question is b. petals.
The corolla is the collective term for all petals, which are usually colorful to attract pollinators. Petals and stamens can fuse together, forming what is known as an adnation, a special type of connation, which is part of the floral structure in many plants. This fusion can help in the placement of pollen on the pollinators.
