A) solanad and asterad type
B) chenopodial and onagrad type
C) caryophyllad and onagrad type
D) solanad and chenopoldial type
Correct Answer: D
Solution :
If the apical cell of 2 celled pro embryo divides transverselly, either the basal cell plays a minor role usually forms suspensor (solanad type) or the basal and apical cell both contribute to the development of embryo (Chenopodial type). When basal cell does not go further division, and the suspensor, if present is derived from apical cell then the embryo development is Caryophyllad type, eg, Caryophyllaceae, Crassulaceae. When the apical cell of the 2 celled pro embryo divides longitudinally Basal cell plays a minor or no role in embryo development- crucifer type or onagrad type, eg, Ranunculaceae, Brassicaceae. When both contribute for embryo development asterad type, eg, Asteraceae, Balsaminaceae etc.
