Activity to show that stem conducts water and
other substances:
1) Take some water in a glass.
2) Add few drops of red ink to the water.
3) Cut the stem of a herb plant from its base.
4) Put it in the glass.
5) It can be observed that some parts of the stem become red indicating that water is being conducted through the stem.
- Observation: You will observe that the colour of the flowers changes from white to red.
- Conclusion: This shows that the stem conducts water from the roots to different parts of the plant. It helps in transportation of water and mineral salts absorbed by the roots to different parts of the plant.
EXTRA INFORMATION✨✨✨
- Plants have two parallel circulatory systems, each made up from a different type of vascular tissue, that transport water, sugar and other nutrients to where they are needed. Ground tissue comprises most of the plant body.
