Some plants increase in height due to changes in specialized regions of cells in the tips of their branches. the processes that result in these changes include meiosis, cell growth and cloning mitosis, zygote formation and cloning meiosis, gamete formation and differentiation mitosis, cell growth and differentiation

The correct answer is : Mitosis, cell growth and differentiation.

Plants increase in height due to the activity of meristem or meristematic tissue. Meristems are tissues which have capacity to divide throughout their life. Meristems are located in the apical meristems, shoot apex and root apex. Meristems divide through mitosis. The daughter cells  enlarge, stretch and differentiate into other types of cells as they mature. This causes some plants to increase in height.

it marks things for degradation via the proteasome. it alters there celluar location.
