Question

Ripened ovary constitutes only an inedible core in
A) Pyrus communis
B) Cocos nucifera
C) Musa sapientum
D) Magnifera indica

Answer 1

The pericarp, produced from the ovary and covering the seeds, is the external, mostly edible layer, while other tissues add to or contain the edible component of some species. The mesocarp, epicarp, endocarp and endocarp can be represented in three layers, from outside to inside.

Complete answer:
First we should know about fruit to answer this question. In botany, the seed-bearing body of flowering plants, produced after flowering from the ovary, is a fruit. The mechanisms by which angiosperms disseminate seeds are fruits. In particular, edible fruits has propagated as a means of seed dispersal and nutrients with the activities of animals and humans in a symbiotic relationship; in fact , humans and several animals are becoming dependent on fruits as a food source
Now, let us find the solution from the options-

Pyrus communis is really the scientific name of a pear that is a fruit form of pome. It's a fake fruit of which the thalamus forms the fleshy portion. The hard stony core surrounding the seed is created by the fertilized ovary.
Coco nucifera seems to be the scientific name for a coconut wherein endosperm is the edible portion. Thus, option B is not the correct option.
Musa sapientum is really the scientific name of a banana consisting of placentas and endoderm, where the core is edible. Thus, option C is not the correct option.
Mangifera Indica is indeed a drupe which forms the core with a craggy hard endocarp and the mesocarp is spongy and edible. Thus, option D is not the correct option.

Thus, the correct answer is option (A) Pyrus communis.

Note: A fruit develops from the maturation with one or maybe more flowers, and everything or part of the fruit constitutes the gynoecium of the flower(s). One or two ovules are within the ovaries where the egg cell holds the megagametophyte.
