Question 2

Distinguish between cell growth and cell differentiation in plants.

Accepted Answer

Answer should discuss key features of cell growth (increase in number of cells by cell division and an increase in cell size by expansion/elongation as well as the key features of cell differentiation (biochemical and structural specialization. Growth is controlled by genes influenced by external and internal environmental signals while differentiation is controlled by altering the activities of certain genes. See pages 717-719.
