Description : Meristematic tissue responsible for increase in girth of tree trunk is (a) intercalary meristem (b) lateral meristem (c) phellogen (d) apical meristem.
Last Answer : (b) lateral meristem
Description : Why do meristematic cells lack vacoules?
Last Answer : The purpose of vacuole is to store food and waste product. Since meristems are young cells and are actively dividing, they do not partcipate actively in food preparetion. Neither they produce large waste and hence lack vacuoles.

Last Answer : (4) Maturation

Description : Tissues are constructed from many distinct cell types that perform different functions in response to signals from each other and the extracellular matrix. During tissue development and tissue regeneration, ... that stem cells undergo when they are required to generate a particular type of cell?
Last Answer : Asymmetric cell division. After asymmetric division, each of the two resulting daughter cells has a unique life course. For example, one daughter cell may differentiate into a specific cell type ( ... cell), whereas the other daughter cell may remain a stem cell with unlimited proliferative ability.
