Explique de que forma a obstrução dos vasos da planta hospedeira pelos biofilmes de bactérias pode levar à morte progressiva das
musickatia [10]

Answer:

Os biofilmes são uma comunidade complexa de microrganismos, que pode ser composta por uma única espécie ou uma combinação de espécies. Os biofilmes são geralmente formados nas superfícies de materiais não vivos ou nos tecidos de organismos vivos; que pode estar externamente nos tecidos vivos dos organismos ou dentro dos tecidos vivos do organismo. Quando os microrganismos formam um biofilme, aumentam suas chances de resistir a anticorpos produzidos pelo organismo e aumentam suas chances de colonização completa do organismo. Algumas doenças são caracterizadas pela presença de biofilmes, que são, na maioria dos casos, a causa da doença.

<em>No caso de obstrução de vasos de plantas hospedeiras por biofilmes bacterianos; os biofilmes se formam na superfície do vaso e aumentam gradualmente de tamanho até que haja uma obstrução completa do vaso da planta. Quando o vaso da planta é eventualmente obstruído, o fluxo de materiais e minerais necessários é obstruído; levando à obstrução das células da raiz de receber materiais vitais e minerais necessários para o crescimento, isso eventualmente leva à morte progressiva das células da raiz.</em>
