{“lesson_id”:0,”category_id”:113,”topic”:”06. Fungi”,”choices”:[“Moss capsules only”,”Two animals”,”A fungus with a photosynthetic partner (alga or cyanobacterium)”,”Only gymnosperm wood”],”correct”:2,”type”:”mcq”,”explain”:”The fungus provides structure; the photobiont provides sugar.”}

{“lesson_id”:0,”category_id”:113,”topic”:”06. Fungi”,”choices”:[“Algal blooms”,”Mutualisms between fungi and plant roots”,”Viral diseases of humans”,”Types of fruit”],”correct”:1,”type”:”mcq”,”explain”:”The fungus gets carbon; the plant gets better mineral (especially phosphate) uptake.”}

{“lesson_id”:0,”category_id”:113,”topic”:”06. Fungi”,”choices”:[“Xylem vessels”,”Feathers”,”Green leaves”,”Hyphae forming a mycelium”],”correct”:3,”type”:”mcq”,”explain”:”A mycelium is the feeding body; a mushroom is often just the fruiting structure.”}

{“lesson_id”:0,”category_id”:113,”topic”:”06. Fungi”,”choices”:[“Silica”,”Peptidoglycan”,”Cellulose only”,”Chitin”],”correct”:3,”type”:”mcq”,”explain”:”Chitin distinguishes fungi from plants.”}

{“lesson_id”:0,”category_id”:113,”topic”:”06. Fungi”,”choices”:[“Heterotrophs that absorb food (often after external digestion)”,”Photosynthetic autotrophs like leaves”,”Chemosynthetic deep-sea plants”,”Filter-feeding animals”],”correct”:0,”type”:”mcq”,”explain”:”Hyphae secrete enzymes and absorb products; they are not green plants.”}

{“lesson_id”:0,”category_id”:108,”topic”:”05. Algae”,”choices”:[“True”,”False”],”correct”:1,”type”:”true_false”,”explain”:”Algae are a mixed set of lineages; they do not form flowers.”}

{“lesson_id”:0,”category_id”:108,”topic”:”05. Algae”,”choices”:[“Cellulose wood”,”Bone”,”Keratin”,”Silica (glass-like frustules)”],”correct”:3,”type”:”mcq”,”explain”:”Silica frustules make diatoms important in sediments and as abrasives historically.”}

{“lesson_id”:0,”category_id”:108,”topic”:”05. Algae”,”choices”:[“Anchors the thallus to rock”,”Fixes nitrogen in nodules”,”Produces seeds”,”Absorbs soil minerals like a tap root”],”correct”:0,”type”:”mcq”,”explain”:”Holdfasts attach; they are not equivalent to vascular plant roots.”}

{“lesson_id”:0,”category_id”:108,”topic”:”05. Algae”,”choices”:[“Pollinate conifer cones only”,”Build only granite”,”Produce much of Earth’s oxygen and form the base of aquatic food webs”,”Replace all xylem”],”correct”:2,”type”:”mcq”,”explain”:”Microscopic algae and cyanobacteria drive marine primary production.”}

{“lesson_id”:0,”category_id”:108,”topic”:”05. Algae”,”choices”:[“Only inside human lungs”,”In marine habitats; some are sources of agar”,”Only on glacier ice as trees”,”Only in deserts”],”correct”:1,”type”:”mcq”,”explain”:”Phycoerythrin lets many live deeper; agar and carrageenan come from red algae.”}
