Question

Boojho had the following parts of a rose plant- a leaf, roots, a branch, a flower, a bud, and pollen grains. Which of them can be used to grow a new rose plant?

Answer 1

Hint: Plant like roses can be grown by means of cutting, which is a process of asexual reproduction in plants. By the use of this method we can produce many rose plants.

Complete answer:
A small part of the plant which is removed by making a cut in the plant with the help of a knife is called “cutting”. Cuttings are used in asexual reproduction in plants. The new plant formed from cutting is exactly the same as the parent plant. Plants like rose and Chrysanthemum are propagated (reproduced) by this method.
A piece of branch having a bud is cut from an existing rose plant with the help of a knife. The lower part of this cutting is buried in the moist soil. After a few days, the end of the cutting is buried in soil which develops roots and later on grows to become a new rose plant.
An advantage of using this method is that we can produce many plants with this. Using this we will not have to wait for flowers and sexual reproduction.

Note:
To produce a rose plant, Boojho will use branches as it can be used in the process of “cutting”. This is advantageous as we can produce many rose plants from this process without waiting for flowers and reproduction.
