  • Ferns are vascular plants that reproduce mainly by:

    {“lesson_id”:0,”category_id”:102,”topic”:”03. Ferns”,”choices”:[“Milk”,”Seeds inside fruits”,”Spores”,”Budding yeast”],”correct”:2,”type”:”mcq”,”explain”:”Sori on fronds release spores; ferns do not make seeds.”}

  • The leafy fern plant you usually see is the:

    {“lesson_id”:0,”category_id”:102,”topic”:”03. Ferns”,”choices”:[“Gametophyte”,”Sporophyte”,”Pollen grain”,”Lichen”],”correct”:1,”type”:”mcq”,”explain”:”The independent sporophyte bears fronds; the gametophyte is a small prothallus.”}

  • Clusters of sporangia on the underside of a frond are called:

    {“lesson_id”:0,”category_id”:102,”topic”:”03. Ferns”,”choices”:[“Nectaries”,”Lenticels”,”Stomata”,”Sori”],”correct”:3,”type”:”mcq”,”explain”:”Sori are groups of spore-producing sporangia.”}

  • A fern prothallus is:

    {“lesson_id”:0,”category_id”:102,”topic”:”03. Ferns”,”choices”:[“A fungal cap”,”A type of seed”,”A woody cone”,”The small haploid gametophyte”],”correct”:3,”type”:”mcq”,”explain”:”The heart-shaped prothallus bears antheridia and archegonia.”}

  • Ferns typically need water for sexual reproduction because:

    {“lesson_id”:0,”category_id”:102,”topic”:”03. Ferns”,”choices”:[“Spores cannot land on soil”,”Sperm usually swim to the egg”,”They lack cell walls”,”They have no chlorophyll”],”correct”:1,”type”:”mcq”,”explain”:”Flagellated sperm need a film of water, so many ferns live in moist sites.”}

  • Young coiled fern leaves are called:

    {“lesson_id”:0,”category_id”:102,”topic”:”03. Ferns”,”choices”:[“Thalli of liverworts”,”Acorns”,”Fiddleheads (circinate vernation)”,”Cones”],”correct”:2,”type”:”mcq”,”explain”:”Fronds unroll from the crozier or fiddlehead.”}

  • Unlike mosses, ferns have:

    {“lesson_id”:0,”category_id”:102,”topic”:”03. Ferns”,”choices”:[“No chlorophyll”,”No embryos”,”True xylem and phloem”,”Chitin walls”],”correct”:2,”type”:”mcq”,”explain”:”Vascular tissue lets fern sporophytes grow larger than mosses.”}

  • True or false: Ferns produce seeds.

    {“lesson_id”:0,”category_id”:102,”topic”:”03. Ferns”,”choices”:[“True”,”False”],”correct”:1,”type”:”true_false”,”explain”:”Ferns are seedless vascular plants.”}
