Vedclass · Answer

(A) Orchid seeds are extremely small and lack an endosperm or any significant food reserves. Because they lack stored nutrients,they cannot germinate on their own in natural soil conditions. To overcome this,the embryos are extracted from the seeds and grown in a specialized nutrient-rich culture medium (in vitro) to support their development. Therefore,both the statement and the reason are true,and the reason correctly explains why the embryo must be extracted and grown in a culture medium.

$S$ - Statement: The embryo from the seed of an orchid is extracted and grown in a culture medium.
$R$ - Reason: The seeds of some plants like orchids do not contain stored food.
