Question

Inferior ovary, syngenesious anther and cypsela fruit, are found in
A.Liliaceae
B.Cruciferae
C.Solanaceae
D.Compositae

Answer 1

Hint: Inferior ovary lies below the flower. Syngenesious anthers are fused anthers. Cypsela fruit is single seeded fruit. It doesn't break open so indexically.

Complete answer:
Let's discuss and find the right answer.
A.Liliaceae: Liliaceae is characterized by presence of 6 free or epiphyllous anther. superior ovary and capsule or berry fruit.its belong to liliid monocot family .If Perianth is green in colour and colored apart from green then it's called sepalaid as in onion and petalaid as in lily respectively. Hence option A is wrong.
B.Cruciferae: Cruciferae has tetradynamous stamen. it's a superior ovary and one chambered and later two chambered silicula that's dehisce along both sutures. It belongs to the asterid dicot family. Its fruit is dry, dehiscent, silicle. Hence option B is wrong.
C.Solanaceae: it is characterized by the presence of epipetalous stamen. it's superior ovary and berry/capsule fruit. Compositae is characterized by presence of syngenesious stamen, inferior ovary and cypsel. Hence option C is inaccurate.
D.Compositae :In Asteraceae or compositae, the ovary of every flower is situated below the attachment of the corolla and stamens. A condition cited as epigynous or inferior. The stamens are syngenesious, that's only anthers are fused into a tube round the style and filaments are free. The flowers produce dry, indehiscent fruits termed as cypsela . The fruits with their hair or scale-like pappus are easily distributed by the wind. Hence option D is correct.
Hence option D: compositae is the correct answer.

Note: The sunflower family has an inferior ovary with cypsela fruit that has hair-like projections thereon called the pappus.When filaments are free and anthert connate in an exceedingly tube, it's termed as syngenesious.
