Question: Cyst nematodes are –
Options:
Ectoparasitic
Sedentary
Migratory
Sedentary endoparasitic
✅Explanation:
Cyst nematodes are plant-parasitic nematodes characterized by their sedentary endoparasitic nature. This means that the female nematodes invade plant roots, establish a feeding site, and become immobile within the root tissue. As they mature, their bodies swell and form a cyst, which is a protective structure filled with eggs. This cyst allows the nematodes to survive harsh conditions and persist in the soil for many years.
