Aggregate fruit is formed from
A. Polycarpellary, apocarpous, gynoecium
B. Polycarpellary, syncarpous, gynoecium
C. An inflorescence
D. Both A and B
Solution
There are different terms used in the plant morphology such as For ovary fused (polycarpellary, apocarpous, syncarpous,) gynoecium( represents the female reproductive unit), and inflorescence(arrangements of the flower). Also, the aggregate fruits are fruits that arise from a single flower that has multiple carpels that are not fused together.
Complete answer: A polycarpellary is a flower with more than one carpel. A monocarpic is a flower with one carpel. A carpel is the female reproductive organ of the flower. As apocarpous and syncarpous ovaries have multiple carpels. But the difference lies in the ways the carpels organize themselves. An apocarpous ovary has its carpels free whereas a syncarpous ovary has fused carpels. A gynoecium is referred to as the female reproductive part of the flower and an androecium is referred to as the male reproductive part An inflorescence is referred to as a bunch of flowers clustered together on a single branch.
-In option A, it is given that aggregate fruit is polycarpellary, apocarpous, and gynoecium which is incorrect. As an aggregate fruit has multiple carpels fused free. But in syncarpous ovaries, carpels are fused.
-In option B, it is given that aggregate fruit is polycarpellary, syncarpous, and gynoecium which is incorrect. A fruit is technically an ovary, known by all, and so is a gynoecium. As aggregate fruit is apocarpous, it cannot be syncarpous. They cannot exist together.
-In option C, an aggregate fruit is referred to as an inflorescence. This statement is false as the fruit is obtained from a single flower.
-In option D, say both A and B. But a flower cannot be apocarpous and syncarpous at the same time. So, the correct option is option A.
Note: Aggregated fruit is a fruit that is obtained from a single flower. The unique feature of this flower is that this flower has more than one ovary. The aggregate fruit is an outcome of more than one ovary combined with each other. The common examples of aggregate fruits are raspberries, strawberries, and blueberries.
