Answer
Vegetative propagation refers to a form of asexual reproduction in plants where new individuals arise from vegetative parts of the parent plant, such as stems, leaves, or roots, without the involvement of seeds.

Answer
One method of vegetative propagation is through runners, which are horizontal stems that grow along the ground. The plant organ involved is the stem.

Answer
An advantage of artificial propagation is that it is generally cheaper or faster, allowing for the rapid production of a large number of plants with desirable traits.
Step 6

Answer
Variation: Reproduction by seed typically results in greater variation among offspring due to genetic recombination, while vegetative propagation produces clones with minimal variation.
Dispersal: Seeds can be dispersed over wider areas, allowing for colonization of new environments, whereas vegetative propagation often results in their offspring being close to the parent plant.
