Therefore linchens are autotrophic. A part of these manufactured carbohydrates are used by the alga in its nutrition, the rest is supplied to the fungal partner. The fungus in turn provides protection to its algae partner from each other.
The algal partner is called phycobiont and the fungal partner is called mycobiont.Microbiology MCQ – 10 (Biology / Life Sciences MCQ: Multiple Choice Questions in Microbiology) (Sample/Model/Practice Questions for CSIR JRF/NET Life Science Examination, ICMR JRF Exam, DBT BET JRF Exam, GATE BT and XL Exam, ICAR JRF NE Exam, PG Entrance Exam, JAM Exam, GS Biology Exam and Medical Entrance Exam).
