Growth from inside a living organism is called intrinsic growth.
Intrinsic vs. Extrinsic Growth
| Feature | Intrinsic Growth | Extrinsic Growth |
|---|---|---|
| Definition | Growth from within a living organism. | Growth due to external accumulation of material. |
| Organisms | Living organisms | Non-living matter |
| Mechanism | Internal biological processes | External accumulation |
| Example | A plant growing taller and adding leaves. | A rock getting bigger as sand accumulates on it. |
| Key Characteristic | A feature of living organisms. | A feature of non-living matter. |
In essence, intrinsic growth is a characteristic feature of living things. It's the result of internal biological processes. On the other hand, extrinsic growth, which happens in non-living things, involves the accumulation of material from the outside.
