Which statement is wrong regarding geometrical growth?

(i) On plotting the length of the organ against time, a linear curve is obtained.

(ii) Mathematically, it is expressed as L t = L 0 + rt.

(iii) Here, both the progeny cells following mitotic cell division retain the ability to divide and continue to do so.

(iv) If we plot the parameter of growth against time, we get a typical sigmoid or S-curve.

(v) A sigmoid curve is a characteristic of living organism growing in a natural environment.

(vi) It is typical for all cells, tissues and organs of a plant.

(vii) The growth can be expressed as W 1 = W 0 e rt .
