Q

The pericarp or fruit wall is differentiated into thin epicarp (skin) fleshy mesocarp and stony endocarp.Hence.it is also called as stone fruit, e.g., Mango, Coconut, Peach, Almond, Trapa etc.

A

Drupe

67
Q

It is a simple, fleshy but false fruit as it is surrounded by a fleshy thalamus which is edible while actual fruit lies within, e.g., apple, pear, loquat

A

Pome

68
Q

Berry is a fleshy fruit in which there is no hard part except the seeds (Fig. 7.13). Pericarp may be differentiated into epicarp, mesocarp and endocarp. One or other of these layers may form pulp in which seeds are embedded which generally gets detached from the placenta.
The fruits derived from superior ovary are called superior or true ones as in brinjal, grape, tomato.

A

Berry

69
Q

This develops from inferior ovary which is unilocular or falsely trilocular having parietal placentation. The seeds remain attached to placenta. The outer ring is very hard as in Cucurbits (

A

Pepo

70
Q

It develops from polycarpellary, syncarpous, superior, multilocuiar ovary with axile placentation. Epicarp forms the leathery peeling, mesocarp is in the form of fibres while the endocarp projects inwards forming distinct chambers from which juicy ingrowths in the form of hair arise which form the edible part, eg. Citrus (Orange, Lemon)

A

Hesperidium

71
Q

These fruits are not fleshy, and their pericarp (fruit wall) is not distinguished into three layers.

A

Dry fruit

Q
