Final answer:
The greatest benefit of asexually propagating plants is that they produce genetically identical plant material, allowing for faster production and adaptation to stable environments. However, genetic uniformity can make them more vulnerable to failures and diseases transmitted through cuttings. The correct option is A) It produces genetically-identical plant material.
Step-by-step explanation:
The greatest benefit of asexually propagating plants is that it produce genetically identical plant material. This means that the offspring are clones of the parent plant and carry the exact same genes. This can be advantageous in stable environments, as all the offspring will be adapted to those conditions.
Additionally, asexual reproduction allows for plants to be produced faster since it does not require the time and energy needed for flower production, pollination, and seed formation. This can be especially helpful for crops that are propagated asexually, such as bananas and potatoes, as it allows for more efficient and quicker production.
While asexual reproduction has its benefits, it is important to note that the genetic uniformity of the clones can make them more susceptible to widespread failure and diseases transmitted through cuttings. The correct option is A) It produces genetically-identical plant material.
