Introduction:
| Type of Growth | Description |
|---|---|
| Human Growth | Babies grow into adults (women or men). |
| Gain in height, weight, and strength during growth. | |
| Full growth takes 18 to 21 years. | |
| Animal Growth | Animals grow into adults over a specific period. |
| For example, hens, cows, and dogs have different growth periods. | |
| Unlike humans, animals have varying growth times. | |
| Plant Growth | Plants grow in the width and height of their stems. |
| Some plants grow branches, while others do not. | |
| Plants continue to grow as long as they live, unlike animals that stop growing. |

Experiment
1. Aim: To observe and measure the growth of a potted sapling over ten to fifteen days.
2. Requirements: potted sapling, thread, peg or nail, and measuring scale.
3. Procedure
- Tie a thread to the tip of the sapling.
- Stretch the thread upwards and tie it to a peg or nail above the plant.
- Ensure the thread remains taut and observe the setup daily for 10–15 days.
4. Observations
- After 10–15 days, the plant's tip is no longer aligned with the thread's original position.
- The plant tip has risen above the thread, indicating vertical growth.
- Any changes in the width of the stem or the formation of new branches can also be noted.
5. Conclusion: The distance between the tip and the thread indicates that the sapling has grown taller. This experiment demonstrates that a plant's growth occurs in both height and width, and some may develop branches.

Food is necessary for growth:
| Category | Description |
|---|---|
| Plants (Photosynthesis) | Plants make food using sunlight, water, soil nutrients, and carbon dioxide. |
| This process is called photosynthesis, which requires chlorophyll (which gives plants a green colour). | |
| During photosynthesis, plants release oxygen into the air. | |
| Animals (Food Search) | Animals cannot make their food because they lack chlorophyll. |
| Herbivores (e.g., goats, sheep, horses) eat plants like grass. | |
| Carnivores (e.g., tigers and lions) hunt other animals that live on plants. |
