Inside every stem, every root, every leaf of a plant runs an invisible highway — two separate lanes, each carrying different cargo, in different directions, at different times. 🌱 One lane carries water and minerals up from the soil. The other carries sugar down from the leaves. This is the vascular system — the plant's equivalent of a circulatory system. Avinto is excited to take you inside the xylem and phloem in Subtopic 4.1: The Vascular System. 🔬 How do plants move materials without a heart or a pump? Type START and find out!
