Meristematic Tissue Experiment – Root Growth in Onion Bulbs
Understanding Meristematic Tissue:
Plants grow because of special cells called meristematic tissues. These are groups of cells that keep dividing to form new cells. You can think of them like a construction team that never stops building new parts of the plant. These cells are undifferentiated, meaning they haven’t yet become a specific part of the plant like a leaf or root hair. They’re found in specific places like the tips of roots and shoots, which is why plants grow longer from their ends.
This experiment shows how root growth in an onion bulb happens due to these meristematic tissues, especially the ones at the root tips, known as the apical meristem.
What Happens in the Experiment:
- Two onion bulbs are placed in Beaker A and Beaker B, both with water.
- Roots start to grow from both bulbs because of active cell division in the meristematic tissue.
- On Day 4, the root tips of Beaker B are cut off. This removes the part of the root responsible for making new cells.
- As a result:
- Beaker A roots continue growing.
- Beaker B roots stop growing after Day 4.
This shows that root growth only happens at the tips, where the apical meristem is located.
Real-Life Data (Root Length in cm):
| Beaker | Day 1 | Day 2 | Day 3 | Day 4 | Day 5 |
|---|---|---|---|---|---|
| A | 1.2 | 2.3 | 3.6 | 4.8 | 5.9 |
| B | 1.1 | 2.1 | 3.4 | Tip Cut | 3.4 |
Summary:
| Beaker | Root Tip | What Happened? |
|---|---|---|
| A | Not cut | Roots kept growing |
| B | Cut on Day 4 | Roots stopped growing |
Key Takeaways:
- Meristematic tissue is the growth zone of a plant.
- Located in root tips, these cells divide continuously.
- Cutting the tip stops further growth because the growth zone is removed.
- This proves the importance of apical meristem in plant development.
Dencity – Perform the Meristematic Tissue Experiment Virtually
With the Dencity Virtual Science Lab, students can safely and easily explore how plants grow and how important meristematic tissues are. Whether it’s Class 9 science or an advanced level, students can observe real-time root growth with interactive simulations.
The Dencity app allows learners to simulate this experiment by:
- Observing root growth in virtual beakers.
- Cutting the root tips digitally and viewing the impact on growth.
- Measuring root lengths over days, just like in a real lab.
This eliminates the need for physical lab setups while ensuring deep understanding through interactive learning.

Frequently Asked Questions (FAQs)
- What is meristematic tissue?
It is a group of actively dividing cells in plants that help them grow in length and thickness. - Why do roots grow from the tip?
Because the tip contains the apical meristem where cells are constantly dividing. - What happens if we cut the root tip?
Root growth stops because the cell-dividing region is removed. - Why was Beaker B’s growth halted after Day 4?
The root tip was cut, removing the apical meristem, so no new cells were formed. - Can we do this experiment at home?
It requires onion bulbs and careful setup, but it’s easier and safer with the Dencity app. - Which class is this experiment for?
This is a Class 9 science experiment. - How does Dencity help with this experiment?
It provides a digital version where students can simulate the experiment and measure growth virtually. - Is Dencity suitable for online classes?
