What is growth?
Growth is the most fundamental and conspicuous characteristic feature of all living organisms, but can not be taken as defining property because non-living things also grow.
Growth can be defined as an irreversible permanent increase in the size of an organ, part, and even a cell.
Growth is a product of metabolism (that is anabolism and catabolism). Therefore occurs at the expense of energy or ATP (Adenosine Tri-Phosphate).

1. | Plant growth is generally indeterminant or unlimited | Animal growth is determinant or limited |
2. | Plant growth is localized | Animal growth is diffused |
3. | The plant grows in two different ways | Animal growth is only primary |
Important points to know:
Plant Growth is localized because they specific locations for their growth activity. Mainly they have three locations of growth that is-
- Apical
- Intercalary
- Lateral
- Accept zygote to embryo development the growth is of diffused types.
