Which of the following is a mechanism for asexual reproduction found in succulents?

Asexual reproduction in succulents often occurs through mechanisms that allow the plant to produce new individuals without the use of seeds. One common and effective method is through leaf cuttings. When a leaf from a succulent is detached and placed in a suitable environment, it can develop roots and eventually grow into a new plant. This ability is largely due to the unique structures and physiological adaptations of succulents, which allow them to store water and nutrients, enabling the leaf to sustain itself long enough to initiate root formation.

While rooting hormone application can aid in developing roots for various types of cuttings, it is not a mechanism of asexual reproduction by itself; rather, it is a technique that can enhance the success of a different reproductive method. Division of tubers is typically associated with plants like potatoes and is not a typical feature of succulents which do not usually produce tubers. Photosynthesis stabilization refers to processes that optimize photosynthesis efficiency but does not directly pertain to the mechanisms of reproduction. Thus, leaf cuttings stand out as a clear and effective way for succulents to reproduce asexually.
