Phases of Growth

  1. Cell Division:
  • It is the first stage of growth. A cell becomes metabolically active at the time of cell division
  • Its genetic material replicates and the cell divides mitotically into daughter cells

 

  1. Cell Elongation:
  • It is the second stage of growth, during this state the daughter cells formed as a result of mitosis enlarge
  • During cell enlargement, new cell wall materials are synthesized in large quantities to cope with the enlargement of the cells

 

  1. Cell Differentiation:
  • Different tissues are formed as a result of differentiation of newly formed cells
  • The form of the cells changes and some cells are differentiated into xylem tracheids and trachea and some other into sieve tubes and companion cells
