Question

Necrotrophs kill host cells in advance of invasion, whereas biotrophs sustain host cell viability during infection.
true or false

Answer 1

True. Necrotrophs are pathogens that typically kill host cells as part of their infection strategy, allowing them to feed on the dead tissue. In contrast, biotrophs establish a relationship with the host that often maintains host cell viability, allowing them to extract nutrients without immediately killing the host cells.
