Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Direct somatic embryogenesis is generally rarer than indirect somatic embryogenesis.
Reason (R): Direct embryogenesis occurs from "Pre-Embryonic Determined Cells" (PEDCs) which are found only in specific embryonic tissues like the scutellum or nucellus.

#Plant Biotechnology

Given below are two statements:
Statement I: In Indirect Somatic Embryogenesis, the explant first proliferates into unorganized callus tissue before differentiating into embryos.
Statement II: IEDCs (Induced Embryogenic Determined Cells) need only a "permissive" signal to start embryogenesis and do not require dedifferentiation.
