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 anther are fused anthers and Cypsela fruit is single seeded fruit which does not break open so indehiscent.

Complete answer
Liliaceae:
(i) It is commonly called the ‘Lily family’.They are monocots, mostly herbs, some are climbers.Perianth is present in this family. If Perianth is green in colour then it is called sepalaid as in onion.
(i) If Perianth is coloured other than green it is known as petalaid as in Lily.
(iii) Gynoecium is tricarpellary, syncarpous, tricular, stigma, trifid, axile placentation, superior ovary.
(iv) Fruit is a capsule, rarely berry.

B. Cruciferae:
(i) Commonly called mustard family.Mostly they are herbs, some shrubs, a few woody.
(ii) Its fruit is dry, dehiscent, silicle.
(iii) Gynoecium – Bicarpellary, united carpels, superior ovary, ovules have parietal placentation.

C. Solanaceae:
(i) It is commonly called “potato family” and mostly herbs, shrubs and rarely small trees.
(ii) Its fruit is a berry or capsule.
(iii) Gynoecium – Bicarpellary, syncarpous, ovary superior, bilocular, placenta swollen with many ovules.

D. Compositae:
(i) It is also called “Asteraceae” and it is the largest family of angiosperms.
(ii) It is commonly called a “sunflower family”.
(iii) In Compositae, calyx is rudimentary or absent called as pappus.
(iv) Gynoecium: 2 united carpels is a bicarpellary inferior ovary, single style with two stigmatic lobes, and has a single ovule and its fruit is achenes or cypsela.

Hence the correct answer is D, Compositae.


Note: It is called Composite Family or Compositae because the flower first seems to be a single large flower but is actually a composite of many smaller flowers. The main feature of the family is the composite flower type in the form of capitula surrounded by involucral bracts.
