Crop Productivity & Modelling

• Statement (I) is False: The scutellum (modified monocot cotyledon) forms the interface between the embryo and the starchy endosperm, secreting hydrolytic enzymes and absorbing digested nutrients. The mesocotyl is the first internode between the scutellar node and coleoptile.
• Statement (II) is True: The coleoptile is a rigid protective sheath that encloses the plumule and emergent first leaves, shielding them from mechanical abrasion as they push through the soil.
• Conclusion: Statement (I) is false but Statement (II) is true.

Correct option: (4) Statement (I) is false but Statement ({I) is true.

• Matching Framework in Examination:
• Castor bean $

ightarrow$ (III) Caryopsis

• Cabbage $

ightarrow$ (IV) Samara

• Cotton $

ightarrow$ (I) Cypsela

• Coffee bean $

ightarrow$ (II) Nut

• Botanical Note: In classical morphology, castor produces a regma/capsule, cabbage a siliqua, cotton a loculicidal capsule, and coffee a drupe; the paper setter matched the specified pairings in Option 1.

Correct option: (1) (A) - (Ill), (B) - (IV), (©)- (), (B) - ()

• GABA-Enriched Genome-Edited Tomato: Developed using CRISPR-Cas9 technology by Sanatech Seed and the University of Tsukuba (Sicilian Rouge High GABA).
• Target Compound: Enriched in $\gamma$-aminobutyric acid (GABA), an inhibitory neurotransmitter in the mammalian central nervous system.
• Mechanism: Targeted deletion of the autoinhibitory domain of glutamate decarboxylase (GAD) enzyme causes sustained enzymatic hyperactivation, dramatically elevating GABA levels in mature fruit to promote cardiovascular relaxation.

Correct option: (2) Gamma amino butyric acid
