👉 Protophloem is a specialized cell in plant cells that plays an essential role in water and nutrient transport. It's also known as the "root cap" or the "capillary ring," which helps to transport water, minerals, and other nutrients from the root to the rest of the plant. In plants, the protophloem acts like a filter, capturing and concentrating these substances before they are transported throughout the plant. This allows for efficient nutrient uptake by roots, which is crucial
