  Lesson-1  Asexual and Sexual Reproduction in Plants CLICK HERE TO ATTEND BOOK BACK ONEWORD ONLINE TEST / புத்தக வினா தேர்வு எழுத இங்கே சொடுக்கவும்.  Reproduction is one of the attributes of living things. Lower plants, microbes and animals reproduce by different methods (fragmentation, gemma, binary fission, budding, regeneration). Organisms reproduce through asexual and sexual methods. Asexual methods in angiosperms occur through natural or artificial methods.  The natural methods take place through vegetative propagules or diaspores. Artificial method of reproduction involves cutting, layering and grafting. Micropropagation is a modern method used to raise new plants.
