{“lesson_id”:5818,”category_id”:0,”topic”:””,”choices”:[“Seed dispersal”,”Water absorption from soil”,”Pollination”,”Gas exchange”],”correct”:3,”type”:”mcq”,”explain”:”Lenticels are pores in bark that permit diffusion of gases to living tissues.”}
-
Phloem mainly transports:
{“lesson_id”:5660,”category_id”:0,”topic”:””,”choices”:[“Pollen tubes”,”Organic food such as sucrose”,”Only mineral ions”,”Only carbon dioxide”],”correct”:1,”type”:”mcq”,”explain”:”Sieve tubes move photosynthate from source to sink.”}
-
True or false: Botany includes the study of algae and, historically, fungi even though fungi are not plants.
{“lesson_id”:0,”category_id”:59,”topic”:”Introduction To Botany”,”choices”:[“True”,”False”],”correct”:0,”type”:”true_false”,”explain”:”Classical botany covered algae and fungi; fungi are now a separate kingdom but still taught beside plant science.”}
-
True or false: Angiosperms enclose their seeds inside fruits.
{“lesson_id”:0,”category_id”:91,”topic”:”01. Flowering Plants”,”choices”:[“True”,”False”],”correct”:0,”type”:”true_false”,”explain”:”That enclosed seed is the defining contrast with gymnosperms.”}
-
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.”}
-
True or false: All algae are plants with flowers.
{“lesson_id”:0,”category_id”:108,”topic”:”05. Algae”,”choices”:[“True”,”False”],”correct”:1,”type”:”true_false”,”explain”:”Algae are a mixed set of lineages; they do not form flowers.”}
-
True or false: A fruit develops after fertilisation from the ovary.
{“lesson_id”:0,”category_id”:64,”topic”:”Life Cycle Of A Flowering Plant”,”choices”:[“True”,”False”],”correct”:0,”type”:”true_false”,”explain”:”Seeds develop from ovules; the ovary wall becomes the fruit.”}
-
True or false: Meristems are regions of ongoing cell division.
{“lesson_id”:0,”category_id”:75,”topic”:”Plant Growth And Development”,”choices”:[“True”,”False”],”correct”:0,”type”:”true_false”,”explain”:”Apical, lateral and intercalary meristems keep plants growing.”}
-
True or false: Plants produce the oxygen we breathe as a by-product of photosynthesis.
{“lesson_id”:0,”category_id”:77,”topic”:”Plants And People”,”choices”:[“True”,”False”],”correct”:0,”type”:”true_false”,”explain”:”Photolysis of water releases O2; phytoplankton and land plants both contribute.”}
-
Besides anchorage, a typical root mainly helps in:
{“lesson_id”:5813,”category_id”:0,”topic”:””,”choices”:[“Photosynthesis”,”Pollen formation”,”Absorption of water and minerals”,”Transpiration of sucrose”],”correct”:2,”type”:”mcq”,”explain”:”Roots absorb water and dissolved minerals from soil; leaves do most photosynthesis.”}
