Types of Growth Curves — NEET Biology

Which of the following statements concerning growth rates and patterns in plants are NOT correct? S1: In arithmetic growth, both daughter cells formed after a mitotic cell division retain the ability to divide. S2: Geometric growth is characterized by an initial lag phase, followed by an exponential rate of increase (log phase). S3: A linear curve is obtained when plotting the parameter of growth against time in systems undergoing geometric growth. S4: The growth rate 'r' in the exponential growth equation (W1 = W0ert) is referred to as the relative growth rate and efficiency index. S5: A typical sigmoid growth curve is characteristic of cells grown in a natural environment and of many higher plants. S6: Growth, whether arithmetic or geometric, is ultimately a reversible permanent increase in size of an organ or its parts.
