Question

Lomentum is characterized 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 fruit of some leguminous plants. It separates maturity into segments in such a way that each segment is containing one seed.

Complete answer:
Constrictions in between the seeds occur in Lomentum. Lomentum is a dry fruit of some leguminous plants which have constrictions between the seeds. The fruit breaks apart at the site of constriction and the seeds are dispersed. Examples of Lomentum are legumes of Acacia and Siliques. Lomentum is also known as loment.
- A seed is a ripened fertilized ovule. In seed, metabolic activities get suspended during the unfavorable conditions. A seed contains embryonic plants, reserve food, and protective coat.
- The Embryo contains radicle and plumule. The radicles are the embryonic root and the plumule is the embryonic shoot.
- Simple fruit is formed from a flower with a single ovary, example- Pea, and Mustard. Aggregate fruit is formed from a flower with two or more ovaries, example- strawberry. Composite fruit is formed from the complete inflorescence, example- Pineapple.
- In Silicula type of fruit, breadth and length are equal.
- When parts other than the ovary take part in the formation of fruit then such fruit is called false fruit. Peanuts and groundnuts are examples of false nuts.
So, the correct answer is, ‘Constrictions in between the seeds.’
Note: Lomentum is a type of schizocarp, which means a dry fruit which contains multiple carpels which separate on maturation. Lomentum is formed from a single carpel.
