multiple choice question
quaking aspen are known to asexually reproduce by forming new clones from their
o leaves.
o stems.
o roots.
o seeds.

Explanation:

Quaking aspen (Populus tremuloides) is a tree species. In asexual reproduction (vegetative reproduction), quaking aspen forms new clones from their roots. The roots can produce new shoots (suckers) which grow into new trees. This is a common form of asexual reproduction in many plant species. Leaves are mainly for photosynthesis, stems are for support and transport (but not the main structure for asexual reproduction in aspen in the context of cloning as described here), and seeds are for sexual reproduction.

Answer:

roots.
