Question

Cyathium and hypanthodium types of inflorescence are similar in having.

• A. Nectar glands
• B. Apical pore
• C. Petaloid bracts
• D. Unisexual flowers

Answer 1

The correct option is D Unisexual flowers

• Cyathium looks like a single flower. A cup-shaped involucre formed by bracts encloses a single female flower and a number of male flowers. Each male flower is represented by single stamen while a single pistil represents a female flower. The example is euphorbia.
  
• Hypanthodium is fleshy receptacle forming a hollow cavity with an apical opening called ostiole. The flowers are developed on an inner wall of the hollow cavity. The male flowers are situated at the top near the opening, at the bottom are situated the female flowers with long styles and in between both are situated short-styled gall flowers which are sterile. The example is ficus. Therefore, both have unisexual flowers.
  

So, the correct answer is 'Unisexual flowers'.
