Describe how new plants arise by asexual reproduction

ANSWERS

• Lower plants/example Bryophyta/pterophyta; produces  spores which develops to new plants; budding  an overgrowth arises from plant drop off; and develops into a  new  plant; common  in lower plants  yeast.
• Fragmentation – e.g Spirogyra; breaks  off  and grows into a new plant 
• Vegetative  propagation:  common in higher plants involves  growth of  new plants from buds/bubils
• Root stem/ tubers/ leaves: possesses buds; which develops to new  plants
• Corns; have terminal buds  that grows vertically  and produce a new  plant
• Runners; have lateral buds that produce new plants
