Assertion: The yellow, fleshy, edible part of the peach is mesocarp which develops from the wall of the ovary.
Reason: Mesocarp is the middle layer of the pericarp between the protective epicarp and stony endocarp.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
Both A and R are true and R is the correct explanation of A.
Reason — A is true because in peach, the fruit wall develops from the ovary wall and is called the pericarp. The pericarp has three layers: Epicarp, Mesocarp, Endocarp. Mesocarp is fleshy, edible part.
R is true as mesocarp is the middle layer of the pericarp between the protective epicarp and stony endocarp.
Therefore, Both A and R are true and R is the correct explanation of A is the correct option.
