Final answer:
Growth resumes from the axillary bud following leaf abscission, as this bud is capable of developing into new growth areas such as branches or floral shoots.d. Axillary bud
Step-by-step explanation:
After leaf abscission, growth will resume from the axillary bud. The axillary bud is a bud located in the axil, which is the stem area where the petiole connects to the stem. This bud is capable of developing into a floral shoot or a branch, taking over the growth after the dominant apical bud has been shed or stopped growing due to processes such as abscission.
