Explanation:
Periplaneta americana, commonly known as American cockroach, is a common household pest. It belongs to the phylum Arthropoda and class Insecta. Let's discuss the given options one by one:
A) Schizocoelom as body cavity:
Periplaneta americana has a schizocoelom as the body cavity. Schizocoelom is a type of body cavity that is found in protostomes. In this type of body cavity formation, the mesoderm splits into two layers, and the space between them forms the body cavity.
B) Indeterminate and radial cleavage during embryonic development:
The given option is incorrect. Periplaneta americana exhibits determinate and spiral cleavage during embryonic development. In determinate cleavage, the fate of each cell is determined early on in embryonic development, while in spiral cleavage, the cells divide at an angle to each other.
C) Exoskeleton composed of N-acetylglucosamine:
The exoskeleton of Periplaneta americana is composed of chitin, a polysaccharide of N-acetylglucosamine. Chitin is a tough, protective, and semitransparent substance that makes up the exoskeleton of arthropods.
D) Metamerically segmented body:
Periplaneta americana has a metamerically segmented body. Metamerism is the segmentation of the body into a series of similar segments, each with its own pair of appendages.
Therefore, the correct answer is option B, i.e., Periplaneta americana does not exhibit indeterminate and radial cleavage during embryonic development.
