Quizplus · Accepted Answer

For a successful graft, the two cambial tissues (the outermost layer of a stem that produces new cells for growth) must fuse together. This allows for the flow of water, nutrients, and carbohydrates between the two sections and enables them to function as a single plant. The other options are incorrect because only the grafted stem needs to form leaves and roots, and the production of seeds is not necessary for graft success. Additionally, the two sections do not need to be from the same species, although they should be relatively closely related for the graft to work well.
