Question

Fruits of Castor (Ricinus) is :
a. Regma
b. Silique
c. Follicle
d. Lomentum

Answer 1

Hint: This is a dry fruit which develops from a superior trior polycarpellary ovary.

Complete Answer:
a. The type of fruit gift in castor bean plant (castor plant) is known as regma. The type of placentation seen in these fruits is stem. The wall of fruit consists of tubercles (spines).
On maturity, the fruit breaks into lobules (by explosion mechanism) and acquires separation.
These separated lobules are spoken as cocci that are connected to a column referred to as stem.

b. Silique, any dry fruit that separates at maturity into 2 or four segments referred to as valves, effort a persistent partition that bears the seeds. The valves stay connected at the highest. A typical siliqua is Associate in Nursing elongated capsule, like in cabbage. A silicle, or silicula, could be a short and broad siliqua, as in a shepherd's purse (Capsella). Each varieties square measure characteristic of plants within the Brassicaceae.

c. In botany, a follicle is a dry unilocular fruit shaped from one pistil, containing 2 or additional seeds. It's typically outlined as dehiscing by a suture so as to unharness seeds, for instance in Consolida (some of the larkspurs), paeony and milkweed (Asclepias).

d. Lomentum may be an easy, dry, dehiscent fruit that splits into single seeded components. The fruit is constricted between the seeds. it's a schizocarpic fruit. Schizocarpic fruit may be a subtype of indehiscent fruits consisting of 2 carpels that at maturity separate on the midplane into 2 one-seeded.

Hence option: ‘A’ is the correct answer.

Note: The fruit splits up into as many parts called cocci as there are carpels. Each part contains one or two seeds which are liberated on the decaying of the dry pericarp.
