    {“lesson_id”:5734,”category_id”:0,”topic”:””,”choices”:[“Cell wall”,”Thylakoid lumen”,”Cytoplasm only”,”Stroma”],”correct”:3,”type”:”mcq”,”explain”:”CO₂ is fixed in the chloroplast stroma using ATP and NADPH from the light reaction.”}

  • Food in phloem generally moves:

    {“lesson_id”:5660,”category_id”:0,”topic”:””,”choices”:[“From source to sink in either direction”,”Only at night”,”Only in xylem”,”Only upward”],”correct”:0,”type”:”mcq”,”explain”:”Direction depends on where sugar is produced or needed.”}

  • Plants store most carbohydrate as:

    {“lesson_id”:0,”category_id”:60,”topic”:”Introduction To Plant”,”choices”:[“Starch”,”Glycogen in liver”,”Chitin granules”,”Urea”],”correct”:0,”type”:”mcq”,”explain”:”Starch in plastids is the usual plant storage polysaccharide.”}

  • The dominant generation in gymnosperms is the:

    {“lesson_id”:0,”category_id”:94,”topic”:”02. Conifers (Gymnosperms)”,”choices”:[“Tiny independent gametophyte plant”,”Algal thallus only”,”Woody sporophyte tree or shrub”,”Fungal hypha”],”correct”:2,”type”:”mcq”,”explain”:”The large plant you see is the diploid sporophyte; gametophytes live inside cones.”}

  • Sphagnum moss is ecologically important because it:

    {“lesson_id”:0,”category_id”:107,”topic”:”04. Mosses And Liverworts”,”choices”:[“Forms peat and holds huge amounts of water”,”Builds coral reefs”,”Produces wheat grain”,”Fixes nitrogen in root nodules like legumes”],”correct”:0,”type”:”mcq”,”explain”:”Peatlands store carbon and water and depend on Sphagnum.”}

  • Mushrooms are typically:

    {“lesson_id”:0,”category_id”:113,”topic”:”06. Fungi”,”choices”:[“Reproductive fruiting bodies that release spores”,”The entire feeding mycelium”,”Plant roots”,”Algal holdfasts”],”correct”:0,”type”:”mcq”,”explain”:”Most of the fungus lives unseen in soil or wood.”}

  • A quadrat is used in plant ecology to:

    {“lesson_id”:0,”category_id”:68,”topic”:”Methods In Botany”,”choices”:[“Pollinate orchids”,”Sample vegetation in a known area”,”Store seeds in liquid nitrogen only”,”Cook food”],”correct”:1,”type”:”mcq”,”explain”:”Repeating quadrats estimates cover or density.”}

  • A tap root system has:

    {“lesson_id”:0,”category_id”:76,”topic”:”Plant Parts”,”choices”:[“Only pneumatophores”,”Only aerial prop roots of maize”,”One dominant primary root”,”No main root, only a dense mat from the start”],”correct”:2,”type”:”mcq”,”explain”:”Carrot and many dicots keep a strong primary root.”}

  • Palynology is the study of:

    {“lesson_id”:0,”category_id”:145,”topic”:”Areas Of Study”,”choices”:[“Tree rings only”,”Root nodules only”,”Algal holdfasts only”,”Pollen and spores”],”correct”:3,”type”:”mcq”,”explain”:”Pollen is used in allergy, honey, fossils and forensics.”}

  • Root nodules of legumes are associated with:

    {“lesson_id”:5813,”category_id”:0,”topic”:””,”choices”:[“Mycorrhizal fungi only”,”Rhizobium and nitrogen fixation”,”Photoperiodism”,”Transpiration pull”],”correct”:1,”type”:”mcq”,”explain”:”Symbiotic Rhizobium in nodules reduces N₂ to ammonia that the plant can use.”}
