Question

Caruncle develops from

• A. Outer integument
• B. Cotyledon
• C. Funiculus
• D. Inner integument

Answer 1

The correct option is A Outer integument

• Seed in many members of the Euphorbiaceae, such as castor, the soft outgrowth capping the hard seed is formed by proliferation of the cells at the tip of the outer integument called caruncle. It is rich in starch and sugars.
• Cotyledons- They are thin, semi-transparent, and oval in outline and are often referred to as seed leaves or first leaves of the seedling.
• Funiculus- It is a stalk-like structure that attaches the ovule to the placenta.
• Inner integument- It forms the tegmen, inner covering of the seed.

So, the correct answer is ‘Outer Integument’.
