Solution

The correct option is C Assertion is correct but Reason is incorrect
In plants, the growth is divided into three main phases, namely phase of cell division, cell elongation and cell maturation. The phase of cell division is called as formative phase. In formative phase, new cells are produced from pre-existing cells through mitosis and not by meiosis. The second phase is phase of elongation. In this, cell enlargement and cell differentiation takes place. In maturation phase, cell differentiate into distinct type of cells and tissues.
Thus, the correct answer is 'Assertion is correct but Reason is incorrect'.
