Defining Adnate
Adnate organs refer to different organs that have fused together. This fusion process is known as adnation. Common examples of adnation can be observed in flowering plants where organs such as stamens, petals, and sepals fuse together. For instance, in a sunflower, the stamens are adnate to the petals.
Defining Connate
Connate organs, on the other hand, are similar organs that have fused together. This fusion process is known as connation. An example of connation can be seen when stamens fuse together or when the sepals of a flower fuse, a condition known as synsepalous. The fusion of petals, known as sympetalous, can be observed in flowers like rose.
