    D) cremocarp                         

    Correct Answer: B

    Solution :

                    Cypsela is dry, indehiscent, single seeded fruit develops from an unilocular, single ovulate inferior ovary of bicarpellary, syncarpous, gynoecium possessing basal placentation. The fruit wall develops from pericarp and thalamus and is thin and remains attached to the seed at one point, eg, Helianthus. Caryopsis are dry, indehiscent, small, single seeded fruit develop from unilocular, single ovuled, superior ovary of multicarpellary gynoecium. It differs from typical achenes as their pericarp is completely fused with the seed coat or testa, eg, Poaceae. Cremocarp are bilocular and two seeded schizocarpic fruits (small, dry) developed from inferior ovary of bicarpellary, syncarpous gynoecium possessing persistant stylopodium, eg, Apiaceae. Berry is a fleshy, indehiscent, few to multiseeded fruit derived from multicarpellary syncarpous gynoecium. The fleshy pericarp of berry consists of epicarp, mesocarp and endocarp.
