Question
In Parthenocarpic type of fruit:
- Seed is absent
- Three layers of pericarp are absent
- Seed coat and pericarp are fused
- Pappus is present
Solution
Parthenocarpy is the natural or artificially induced production of fruit without fertilization of ovules, which makes the fruit seedless.
Let's analyze each statement:
-
Seed is absent: This is true. In parthenocarpic fruits, since there is no fertilization, no seeds are formed.
-
Three layers of pericarp are absent: This is false. The pericarp, which is the fruit wall developed from the ovary, is usually present in parthenocarpic fruits. It consists of three layers: the exocarp (outer layer), mesocarp (middle layer), and endocarp (inner layer).
-
Seed coat and pericarp are fused: This is false. Since there are no seeds in parthenocarpic fruits, there is no seed coat to fuse with the pericarp.
-
Pappus is present: This is generally false. A pappus is a modified calyx, the function of which is to aid in the dispersal of the fruit. It is typically found in the Asteraceae family. Most parthenocarpic fruits do not have a pappus, but it depends on the specific type of fruit.
So, the correct statement is "Seed is absent".
