If a gynoecium has multiple carpels “fused” into a single structure, it is syncarpous. A syncarpous gynoecium can sometimes appear very much like a monocarpous gynoecium.
Do blossoms turn into fruit?
At the beginning of the summer, apple trees are covered in blossoms. To become fruit the blossoms must be cross-pollinated, generally by bees and other insects, before being fertilized. … Once fertilized, the blossom falls off, giving way for the ovary to grow and expand into a fruit.

Is Hibiscus Apocarpous and Syncarpous?
It is syncarpous (Gk syn- with, karpos- fruit) if carpels are fused, e.g., Hibiscus, Papaver (Poppy). … Parts of styles and stigmas can be free, e.g., Hibiscus.
