Question

An aggregate fruit is one which develops from:

• A. Multicarpellary apocarpus gynoecium
• B. Complete inflorescence
• C. Multicarpellary superior ovary
• D. Multicarpellary syncarpous gynoecium

Answer 1

The Correct Option is A

An aggregate fruit is a type of fruit that develops from a cluster of ovaries that come from a single flower. The correct answer to the question is: Multicarpellary apocarpus gynoecium.

Here’s the step-by-step explanation:

1. Definition of Terms:
   • Gynoecium: The female reproductive part of a flower, consisting of one or more carpels.
   • Multicarpellary: Refers to having multiple carpels.
   • Apocarpus Gynoecium: A condition where the carpels are free and separate from each other.
2. Understanding Aggregate Fruits:
   • An aggregate fruit forms when multiple separate carpels from the same flower mature into individual fruits that cluster together on a single receptacle. This is typical of a multicarpellary apocarpous gynoecium.
3. Examination of Options:
   • Multicarpellary apocarpus gynoecium: Correct option as explained above. It occurs when the flower has multiple separate (apo-) carpels.
   • Complete inflorescence: This refers to a group of flowers arranged on a stem, which is not responsible for producing aggregate fruits.
   • Multicarpellary superior ovary: In this case, the ovary is above other floral parts but does not necessarily mean they are free or apocarpous.
   • Multicarpellary syncarpous gynoecium: This arises when the carpels are fused together, leading to a different type of fruit called a compound fruit, not an aggregate fruit.

Thus, the concept of aggregate fruits aligns accurately with the multicarpellary apocarpus gynoecium, making it the correct answer.
