  • True or false: Stems never store food.

    {“lesson_id”:5818,”category_id”:0,”topic”:””,”choices”:[“True”,”False”],”correct”:1,”type”:”true_false”,”explain”:”Many stems store food, including tubers, rhizomes and corms.”}

  • Vessels are characteristic of:

    {“lesson_id”:5660,”category_id”:0,”topic”:””,”choices”:[“Algae”,”Most angiosperms”,”Mosses”,”Most gymnosperms”],”correct”:1,”type”:”mcq”,”explain”:”Efficient vessel elements are typical of flowering plants; many gymnosperms have tracheids only.”}

  • Unlike most animals, plants typically:

    {“lesson_id”:0,”category_id”:60,”topic”:”Introduction To Plant”,”choices”:[“Are sessile and grow throughout life at meristems”,”Lack cell walls”,”Have no DNA”,”Cannot reproduce”],”correct”:0,”type”:”mcq”,”explain”:”Modular, indeterminate growth from meristems is a plant hallmark.”}

  • Conifer wood is commercially important as:

    {“lesson_id”:0,”category_id”:94,”topic”:”02. Conifers (Gymnosperms)”,”choices”:[“Only rubber latex”,”Only cotton fibre”,”Softwood timber”,”Only wheat grain”],”correct”:2,”type”:”mcq”,”explain”:”Gymnosperm xylem supplies much construction lumber and paper pulp.”}

  • Moss sperm typically reach the egg by:

    {“lesson_id”:0,”category_id”:107,”topic”:”04. Mosses And Liverworts”,”choices”:[“Swimming in a film of water”,”Wind only”,”Phloem translocation”,”Insect pollination of a fruit”],”correct”:0,”type”:”mcq”,”explain”:”Free water is required for fertilisation, so mosses thrive in moist habitats.”}

  • Mycorrhizae are:

    {“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.”}

  • Field botanists often record:

    {“lesson_id”:0,”category_id”:68,”topic”:”Methods In Botany”,”choices”:[“Only stellar magnitude”,”Only stock prices”,”Only blood groups”,”Habitat, location, date and associated species”],”correct”:3,”type”:”mcq”,”explain”:”Good labels make a specimen scientifically useful.”}

  • Fruits primarily help in:

    {“lesson_id”:0,”category_id”:76,”topic”:”Plant Parts”,”choices”:[“Photosynthesis in shade”,”Protecting seeds and often aiding dispersal”,”Forming root caps”,”N2 fixation”],”correct”:1,”type”:”mcq”,”explain”:”Fleshy fruits attract animals; winged fruits ride wind.”}

  • Genetics in botany includes:

    {“lesson_id”:0,”category_id”:145,”topic”:”Areas Of Study”,”choices”:[“Only insect taxonomy”,”Only wood density tables”,”Inheritance, chromosomes and plant breeding”,”Only rainfall maps”],”correct”:2,”type”:”mcq”,”explain”:”Mendel worked with pea plants; crop breeding applies genetics.”}

  • The Casparian strip occurs in the:

    {“lesson_id”:5813,”category_id”:0,”topic”:””,”choices”:[“Endodermis”,”Pith”,”Epidermis”,”Root cap”],”correct”:0,”type”:”mcq”,”explain”:”Suberised Casparian strips in endodermal walls force water through the protoplast, helping selective uptake.”}
