Juicy hair-like structures observed in the lemon fruit develop from
- exocarp
- mesocarp
- endocarp
- mesocarp and endocarp.
Answer
(3) endocarp
Solution
Lemon is a hesperidium (berry-type fruit): the outer rind is the exocarp (flavedo), the white spongy layer is the mesocarp (albedo) and the membranous lining of the segments is the endocarp.
⇒ The juicy, multicellular hair-like juice sacs project from the inner surface of the endocarp into the locules.
∴ The edible juicy hairs develop from the endocarp.
