Answer
Vegetative propagation refers to a type of asexual reproduction in plants where new individuals are produced from the vegetative parts of the plant, such as stems, roots, or leaves, without the involvement of gametes, resulting in offspring that are genetically identical to the parent.
Step 2
Give two features of vegetative propagation.

Answer
There are no gametes produced, which means reproduction occurs without seeds.
Since it involves only one parent, there is no variation in the offspring, leading to identical genetic copies.
Step 3
Give one example of natural vegetative propagation from a leaf and one example from a bud.

Answer
Natural vegetative propagation from a leaf can be seen in Begonias, where new plants can grow from leaf cuttings. An example from a bud is the formation of bulbs, such as in onions, which develop from the buds on the parent plant.

Answer
A significant benefit of artificial vegetative propagation is that it can produce rapid or more reliable traits in the offspring, ensuring desirable characteristics are maintained across generations.
