Question

Assertion: Wheat is a caryopsis.
Reason: Its pericarp is well differentiated.

• A. If both A and R are true and R is correct explanation of A.
• B. If both A and R are true but R is not correct explanation of A.
• C. If A is true and R is wrong.
• D. If A and R both are false.
• E. If A is false and R is true.

Answer 1

The correct option is C If A is true and R is wrong.

A caryopsis is a type of simple dry fruit that is monocarpellate and indehiscent and resembles an achene, except that in a caryopsis the pericarp is fused with the thin seed coat. Thus, inthis case pericarp can not be well differentiated. Wheat is a caryopsis but the reason given for this assertion is incorrect.
The caryopsis is popularly called as a grain and is the fruit typical of the family Poaceae (or Gramineae), which includes wheat, rice, and corn. The term grain is also used in a more general sense as synonymous with cereal. Considering that the fruit wall and the seed are intimately fused into a single unit and the caryopsis or grain is a dry fruit.
Therefore, the correct answer is option C.
