📚noun

biotrophs

🗣️

DEFINITION

parasitic organisms, such as fungi or bacteria, that require living host tissues to grow and reproduce

EXAMPLE SENTENCES

Plant pathologists studied how biotrophs infect living crop leaves without killing host cells immediately during development. Unlike organisms that feed on dead matter, obligate biotrophs cannot survive or reproduce outside living host tissues. Agricultural scientists developed resistant crop varieties designed to block the specialized feeding structures used by harmful biotrophs. Fungal species classified as biotrophs absorb essential nutrients directly from host cell walls while maintaining host viability. Microscopic analysis revealed that specific cereal rusts act as biotrophs, extracting energy from active plant cells during infection.
