The cells in the meristematic phase are rich in protoplasm with large nuclei and primary cell walls. (This describes the characteristics of cells in the initial phase of growth.) During the arithmetic growth phase, following mitotic cell division, only one daughter cell continues to divide. (This represents the early phase of growth where cell division is occurring.)
The elongation phase represented increased vacuolation and new cell wall deposition. (This describes the subsequent phase where cells elongate and undergo structural changes.) The exponential phase of the sigmoid curve represents a period where ert holds true and displays the maximum efficiency index of the plant. (This statement summarises the phase where exponential growth occurs and maximum efficiency is reached.)
So, the correct sequence is .
