{“lesson_id”:0,”category_id”:64,”topic”:”Life Cycle Of A Flowering Plant”,”choices”:[“Leaf palisade”,”Stigma”,”Root cap”,”Xylem vessel”],”correct”:1,”type”:”mcq”,”explain”:”Pollen must land on a receptive stigma before a pollen tube can grow.”}

{“lesson_id”:0,”category_id”:64,”topic”:”Life Cycle Of A Flowering Plant”,”choices”:[“A petal falls”,”A sperm nucleus fuses with the egg in the ovule”,”A leaf photosynthesises”,”A seed is eaten”],”correct”:1,”type”:”mcq”,”explain”:”The pollen tube delivers sperm to the embryo sac.”}

{“lesson_id”:0,”category_id”:64,”topic”:”Life Cycle Of A Flowering Plant”,”choices”:[“An embryo and stored food, protected by a seed coat”,”Only pollen”,”Only a flower bud”,”Only a fruit wall”],”correct”:0,”type”:”mcq”,”explain”:”The embryo is the young sporophyte; endosperm or cotyledons supply food.”}
