Which term describes carpels fused into a single ovary?

• A. Apocarpous
• B. Perianth
• C. Axile Placentation
• D. Syncarpous

Answer: (D)

When the carpels fuse to form one ovary, the gynoecium is syncarpous. The term comes from syn-, meaning together, and carpus/carpel. This fusion produces a single ovary that may contain multiple locules and often a common stigma, distinguishing it from a set of separate ovaries. Apocarpous describes that separate carpels remain independent, forming multiple simple pistils rather than one fused ovary. Perianth refers to the outer floral envelope, not to the fusion of carpels. Axile placentation describes how ovules are arranged within a multiloculed ovary, relating to placement rather than to whether the carpels are fused. So the term for carpels fused into a single ovary is syncarpous.
