Question

Quizplus · Accepted Answer

Vascular plants need phloem because not all parts of the plant are independently autotrophic. Unlike xylem, which transports water and minerals, phloem is responsible for transporting organic compounds like amino acids and sugars throughout the plant. This is important because some parts of the plant, like the roots, cannot produce enough energy through photosynthesis to sustain themselves and rely on these transported organic compounds for energy. Thus, phloem is necessary for the survival of vascular plants.
