Question

Juicy hair-like structures observed in the lemon develop from:
 A) Exocarp
B) Mesocarp
C) Endocarp
D) Mesocarp and Endocarp

Answer 1

Hint:The lemon (Citrus lemon) is a hesperidium, a berry with a rugged and leathery skin. The exocarp (peel) contains volatile oil glands (essential oils) in pits.

Complete answer:
Juicy hair-like structures present in the lemon fruit develop from endocarp. Endocarp is the inner layer of the pericarp (or fruits), which directly encompasses the seeds. The fleshy inside (endocarp) is made out of separate sections (carpels) loaded up with liquid filled sacs (vesicles) that are really specific hair cells. The consumable mash (endocarp) is contained in a peel (epicarp or exocarp) which is very thick and not edible in the exacting sense (since it doesn't have a decent taste, aside from in the kumquat).

The epicarp comprises an epidermis made of a variable (depending on the variety, the climatic conditions and the maturing) amount of epicuticular waxes that have the shape of little plates. In this first epidermic layer typically a microflora lives, predominantly comprising fungi and microscopic organisms, more abundant in damp atmospheres. Along these lines, before the cycle of extraction of the juice and of the essential oils, a sufficient washing of the fruit is consistently important to dispense with potential pollutants originating from the outside of the fruit.

It could be membranous as in citrus where it is the main part consumed, In citrus fruit, the endocarp is isolated and separated into sections, which are called as segments. These segments are loaded up with juice vesicles, which contain the juice of the fruit.

Hence the correct answer is option C, i.e. Endocarp.

Note:In expansion to seed protection and dispersal, the endocarp likewise assumes a significant part in sustaining and communicating with the developing seeds. Seeds are associated with the maternal fruit tissue through an umbilical structure called the funiculus.
