  • Companion cells are closely associated with:

    {“lesson_id”:5660,”category_id”:0,”topic”:””,”choices”:[“Sieve tubes”,”Guard cells only”,”Tracheids”,”Root cap cells”],”correct”:0,”type”:”mcq”,”explain”:”Companion cells load and unload sieve tubes and keep them alive.”}

  • The organelle that performs photosynthesis is the:

    {“lesson_id”:0,”category_id”:60,”topic”:”Introduction To Plant”,”choices”:[“Mitochondrion”,”Chloroplast”,”Centriole”,”Lysosome”],”correct”:1,”type”:”mcq”,”explain”:”Chloroplasts contain chlorophyll and the photosynthetic machinery.”}

  • Pollen in conifers is typically produced in:

    {“lesson_id”:0,”category_id”:94,”topic”:”02. Conifers (Gymnosperms)”,”choices”:[“Male cones”,”Root nodules”,”Algal holdfasts”,”Mushrooms”],”correct”:0,”type”:”mcq”,”explain”:”Microsporangiate (pollen) cones release pollen, often wind-borne.”}

  • Bryophytes absorb water mainly:

    {“lesson_id”:0,”category_id”:107,”topic”:”04. Mosses And Liverworts”,”choices”:[“Through vessels like trees”,”Through deep tap roots”,”Only through flowers”,”Over the body surface (they have rhizoids, not true roots)”],”correct”:3,”type”:”mcq”,”explain”:”Rhizoids anchor but do little true vascular uptake.”}

  • The vegetative body of a typical fungus is a network of:
