Juicy hair-like structures observed in the lemon fruit develop from : -
A
Exocarp
B
Mesocarp
C
Endocarp
D
Mesocarp and endocarp
The answer is C.
Solution
The lemon (like orange) is a special type of berry called a hesperidium, developing from a multicarpellary, syncarpous superior ovary. Its pericarp has three parts: the outer glandular epicarp (rind with oil glands), a white spongy mesocarp, and a thin membranous endocarp lining the chambers (segments). Juicy, hair-like outgrowths (juice sacs) arise from the inner surface of the endocarp and fill the chambers. These are the edible part. So the juicy hairs develop from the endocarp.
