Plants rely on specialized tissues for transport and specific mineral ions to maintain healthy physiological functions.
Identify the specialized plant tissue responsible for the translocation of dissolved sugars, such as sucrose, from the leaves to the rest of the plant.
A deficiency of magnesium ions (Mg2+\text{Mg}^{2+}Mg2+) in the soil results in plants showing signs of severe chlorosis (yellowing of the leaves) and stunted growth. Explain how a deficiency of magnesium ions leads to stunted growth in the plant.
