Question: The shape of a female nematode may be…………
Options:
Kidney-shaped
Apple-shaped
Melon-shaped
All of these
✅Explanation:
The shape of female nematodes can vary significantly depending on the species and their life stage. While the basic body plan of nematodes is typically cylindrical and elongated, female nematodes can undergo morphological changes, especially during their reproductive stage, which can lead to various shapes.
Kidney-shaped: Some female nematodes, especially cyst nematodes like Heterodera spp. and Globodera spp., develop a swollen, kidney-shaped body after fertilization as they become filled with eggs.
Apple-shaped: Certain root-knot nematodes (Meloidogyne spp.) can develop a rounded, apple-like shape as they mature and their bodies swell with eggs.
Melon-shaped: Other nematodes, like reniform nematodes (Rotylenchulus reniformis), can also develop a rounded, melon-like shape during their reproductive stage.
