Question
Explain asexual reproduction in plants.
✓

Answer

(i) Reproduction in plants with the help of vegetative parts like root, stem, leaf and bud is called as vegetative reproduction.
(ii)Vegetative propagation in potatoes is performed with the help of eyes present on tuber whereas in Bryophyllum, it is performed with the help of buds present on leaf margin.
(iii)In case of plants like sugarcane and grasses, vegetative propagation occurs with the help of buds present on nodes.
(iv)Plants like carrot and raddish perform vegetative propagation with the help of roots.
(v)Plants like spirogyra reproduces asexually by fragmentation.
(vi)When there is plenty of water and nutrients available to spirogyra, its filaments grow up very fast and break up into many small fragments. Each fragment starts to live independently as a new spirogyra fibre.
