A small part of the shoot of a plant is removed with a sharp knife. When the lower end of this small part of the shoot is buried in moist soil, it gradually develops roots and shoots and grows to become a new plant.
Give one advantage of this (cutting) method of producing new plants.
Important Questions on How Do Organisms Reproduce
A small part of the shoot of a plant is removed with a sharp knife. When the lower end of this small part of the shoot is buried in moist soil, it gradually develops roots and shoots and grows to become a new plant.
State whether it is a sexual method of reproduction or an asexual method. Why?
What special name can be given to the genetically identical new plants produced by this (cutting) technique? (Callus/ Clones)
When the branches of a plant growing in the field are pulled towards the ground and a part of them is covered with moist soil (leaving the tips of the branches exposed above the ground), then after some time new roots develop from the parts of branches buried in the soil. On cutting these branches from the parent plant, new plants are produced from the cut parts of branches that had developed roots.
What is this method of propagation of plants known as? (Grafting/Layering/Cutting)
When the branches of a plant growing in the field are pulled towards the ground and a part of them is covered with moist soil (leaving the tips of the branches exposed above the ground), then after some time new roots develop from the parts of branches buried in the soil. On cutting these branches from the parent plant, new plants are produced from the cut parts of branches which had developed roots.
What type of branches should a plant have to be able to be propagated by this method ?
When the branches of a plant growing in the field are pulled towards the ground and a part of them is covered with moist soil (leaving the tips of the branches exposed above the ground), then after some time new roots develop from the parts of branches buried in the soil. On cutting these branches from the parent plant, new plants are produced from the cut parts of branches which had developed roots.
Name any two plants which are grown for their flowers and propagated by this method.

Name one plant which gets propagated by this method naturally by forming runners (soft horizontal stems running above the ground).
A worm X found in freshwater and slow-moving streams has been accidentally cut into three pieces. It was observed that in due course of time, each cut piece of the worm develops to become a complete worm by growing all the missing parts.
Name the worm X which can exhibit this phenomenon of making a complete worm from its cut body parts. (Planaria/Agaricus)
