Question

The fruit of sorghum is known as-
A. cypsela
B. Caryopsis
C. Achene
D. Legume

Answer 1

Hint: The fruit of Sorghum is also known as a caryopsis. It is a single seed. In this, the pericarp is fused with the seed coat completely and forms a joint structure termed as a grain.

 Complete answer:
Option A is cypsela which is a dry single-seeded fruit. It does not split open during seed dispersal. It is formed from a double ovary in which only one of its ovules develops into a seed. It is similar to an achene, a characteristic of the family Compositae (Asteraceae), such as the dandelion.

Option B is caryopsis. It is a type of simple dry fruit and it is monocarpellate which means that it is formed from a single carpel and indehiscent that means not opening at maturity. It also resembles an achene, except the pericarp is fused with the thin seed coat.

Option C is an achene. It is a type of simple dry fruit. It could be produced by many species of flowering plants. Achenes are also monocarpellate and indehiscent. Achenes contain a single seed and this seed nearly fills the pericarp but does not adhere to it.

Option D is A legume that is a plant in the family Fabaceae (or Leguminosae). It could also be a fruit or seed of such a plant. The seed is called a pulse when used as a dry grain. These plants are grown agriculturally, primarily for human consumption, livestock forage, and silage. They are also used as soil-enhancing green manure.

So, the answer is option B, Caryopsis.

Note: Sorghum is a nutrient-packed grain that could be used in many ways. It's rich in vitamins and minerals. It comprises B vitamins, magnesium, potassium, phosphorus, iron, and zinc. Therefore, it is an excellent source of fiber, antioxidants, and protein.
