Which term describes the fusion of multiple carpels into a single ovary?

Explanation:
Understanding how carpels fuse to form the ovary helps explain this term. When several carpels join together to create one ovary, the gynoecium is called syncarpous. In this arrangement, you still have multiple carpels, but they are fused into a single ovary that may have multiple internal compartments (locules). This contrasts with apocarpous, where each carpel remains separate and forms its own ovary, giving multiple distinct fruits. The other terms don’t describe this fusion: the perianth is the outer floral envelope (sepals and petals), and placentation refers to how ovules are arranged inside an ovary.
