| Read the assertion and reason carefully: |
| Assertion : The embryo which is capable to germinate should have well-developed radicle plumule and one or two cotyledons. |
| Reason : In the Orobanchaceae and Orchidaceae the embryo never differentiates a true radicle, plumule and cotyledons, but can germinate. |
A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C) If the assertion is true but the reason is false
D) If both the assertion and reason are false
E) If the assertion is false but reason is true
Correct Answer: B
Solution :
Irrespective of its mode of development a nature embryo generally possesses an embryonic root (radicle) a embryonic shoot (plumule) and one or two cotyledons. However, some groups of plants are characterised by the presence of reduced embryos, lacking the differentiation of these organs, for example, the plants of Balanophoraceae, Orchidaceae, Orobanchceae.
