Question

Lomentum is a fruit characterised by
A. Dehiscence from both sutures
B. Dehiscence from one suture
C. Indehiscent nature
D. Constrictions in between the seeds

Answer 1

Hint:Lomentum is a kind of dry dehiscent fruit produced from a single carpel but separated into single-seeded compartments by constrictions between the seeds

Complete answer:
A loment or lomentum is a type of indehiscent legume fruit that breaks apart at constrictions between segments so that each segment contains one seed. It is a form of schizocarp. Tick trefoil (Desmodium) and sweet vetch (Hedysarum) are two varieties which show this type of fruit, located particularly in the Hedysareae tribe of the Fabaceae family.
Momentum is a schizocarpic fruit in which the fruit is attached by the seeds. The dehiscence of both sutures is seen in the legumes. Dehiscence from one suture can be seen in follicle fruits. Characteristic of these fruits is that their pericarp is split when ripened and the seeds disperse. Indehiscent fruits contain achene, caryopsis, cypsela, samara and nutmeg.
Lomentum is a dry fruit of some leguminous plants, with constrictions between the seeds and dividing at maturity into single-seeded segments. A loment or lomentum is a type of indehiscent legume fruit that breaks apart at constrictions between segments so that each segment contains one seed. It is a form of schizocarp.

Thus, the correct answer is option D. i.e., Constrictions in between the seeds.

Note:In indehiscent fruits, pericarp does not split when ripened and the seeds remain inside. In dehiscent fruit, pericarp is split when ripened and the seeds disperse. The schizocarpic fruit is restricted between the seeds and is generally broken down into parts having one or more seeds.
