Typical growth curve in plants is :
Correct answer: C. Sigmoid
- A. Stairsteps shaped
- B. Parabolic
- C. Sigmoid
- D. Linear
Explanation
Geometric growth cannot be sustained for long in natural conditions. Limited nutrient availability slows down the growth. It leads to a stationary phase or even a decline. Plotting the growth against time gives a typical sigmoid or S-curve. The sigmoid curve of growth is typical of most organisms in their natural environment including plants. An idealized sigmoid growth curve is drawn below:

About Growth and Development
Embryonic development covers fertilization, cleavage, formation of the blastula and gastrula, germ layers, organ formation and differentiation. Regeneration describes the replacement of lost tissues or body parts, whereas ageing involves gradual cellular and physiological changes linked to reduced repair, altered metabolism and declining organ function.
