Explanation:
The correct answer is option 'A', which states that the feature is not found in Periplaneta americana.
Periplaneta americana:
Periplaneta americana, commonly known as the American cockroach, is a large species of cockroach native to tropical and subtropical regions. It is an important model organism for studying insect biology and is widely used in research.
Features of Periplaneta americana:
1. Embryonic development: Periplaneta americana undergoes embryonic development. However, it does not exhibit indeterminate and radial cleavage during this process. Instead, it undergoes determinate and superficial cleavage. This means that the fate of each cell is determined early in development, and the cells are arranged in a single layer on the surface of the egg.
2. Schizocoelom: Periplaneta americana has a schizocoelom as its body cavity. Schizocoelom is a type of coelom formation where the body cavity is formed by splitting of the mesoderm. In this process, the mesoderm splits into two layers, creating a cavity between them.
3. Metamerically segmented body: Periplaneta americana has a metamerically segmented body. This means that its body is divided into distinct segments or metameres. Each segment usually has a pair of legs, and the segments are arranged in a linear series along the body.
4. Exoskeleton composed of N-acetyl glucose-amine: Periplaneta americana has an exoskeleton composed of chitin, which is a modified form of N-acetylglucosamine. The exoskeleton provides protection and support to the insect's body.
Conclusion:
In conclusion, Periplaneta americana does not exhibit indeterminate and radial cleavage during embryonic development. Instead, it undergoes determinate and superficial cleavage. The other features mentioned, such as schizocoelom, metamerically segmented body, and exoskeleton composed of N-acetyl glucosamine, are present in Periplaneta americana.
The correct answer is option 'A', which states that the feature is not found in Periplaneta americana.
