Plant growth is generally indeterminate because of:
| 1. | Phenotypic plasticity |
| 2. | Geometrical growth shown by all organs |
| 3. | Presence of meristems |
| 4. | Terminally differentiated cells |
If we plot the parameter of growth against time for a living organism growing in a natural environment, the shaped of the curve is expected to be:
| 1. | Linear | 2. | Rectangular hyperbola |
| 3. | Sigmoid | 4. | Bell shaped |
