🎯 Welcome to Episode 85 of our PSLE Science series! Today, we're exploring a seemingly strange observation in Plant Transport: why does a fruit grow bigger if the food-carrying tubes (phloem) below it are removed? This question tests your understanding of how food is transported and stored in plants.
📌 What You’ll Learn
✅ The function of food-carrying tubes (phloem): transporting sugar (food) from the leaves to all other parts, including roots and fruits.
✅ What happens to the sugar when its downward path is blocked by the removal of the phloem?
✅ The key reason why the fruit above the removed section swells and becomes significantly bigger.
✅ How to design a controlled experiment, including a control setup, to verify this observation.
🎥 Watch closely as we explain this classic ringing experiment and how it proves the role of phloem in a plant's transport system!
