It is the most common artificial vegetative propagation method, where pieces of the "parent" plant are removed and placed in a suitable environment so that they can grow into a whole new plant.
Define the process of cutting in vegetative propagation.
100
It is a form of asexual reproduction of a plant. Only one plant is involved and the offspring is the result of one parent.
What do you understand by the term vegetative propagation?
100
Plants raised by vegetative propagation can bear flowers and fruits earlier than those produced by seeds.
What is one advantage of propagating plants vegetatively?
100
These are examples of plants which have lost the capacity to produce seeds and can be grown easily through vegetative propagation
What is the advantage of growing plants like banana, orange, rose and jasmine through vegetative propagation?
100
Plants grown by this method lose vigour and become prone to diseases.
What is one disadvantage of vegetative propagation?
300
They use artificial means to produce plants that are identical to the parent plant.
Who does the "they" refer to in the given statement?
300
In this method, the scion is the above ground part of one plant. The scion is attached to the stock which is the rooted part of the second plant.
Name the two parts of the plant involved in the method of grafting.
300
The buds produced in the notches along its margins fall on the soil and develop into new plants.
How do the leaves of the bryophyllum plant produce new plants?
300
It is an advantage as plants skip the risky seedling stage in which a number of plants die under adverse conditions.
What is the advantage of vegetative propagation with regards to germination of seeds under adverse conditions?
300
Since many plants are produced, it results in overcrowding and lack of nutrients.
Give a disadvantage of vegetative propagation with regards to the number of plants produced.
500
Under natural vegetative propagation, plants grow using the parts mentioned in the question.
What are the uses of parts like stems, roots, leaves and bulbs under natural vegetation?
500
In this method, a shoot of a parent plant is bent until it can be covered by soil. The tip of the shoot remains above ground. New roots and eventually a new plant will grow. These plants can then be separated.
How does the method of layering work?
500
It is an advantage of vegetative propagation.
Critically analyse the given statement as a result of vegetative propagation - All plants produced are genetically similar enough to the parent plant to have all its characteristics.
500
In this method, new plants are grown by removing tissues or separating cells from the growing tip of the plant. It is similar to artificial vegetative propagation as many plants can be grown from one parent and it is commonly used for ornamental plants.
What is tissue culture and how is it similar to artificial vegetative propagation?
500
It is an advantage as beneficial traits from the parent plant are preserved. It is a disadvantage as plants become more prone to diseases due to lack of genetic variation.
The fact that all plants propagated vegetatively are genetically more or less the exact copy of the parent plant sometimes proves to be both an advantage as well as disadvantage. Justify giving reasons.
