Besides the products of photosynthesis, what other substances does the phloem transport, and where are these substances particularly delivered?

In addition to transporting products of photosynthesis, the phloem also transports other substances such as hormones, amino acids, and signaling molecules. These substances are particularly delivered to areas of the plant where they are needed for growth, development, and coordination of physiological processes. Hormones, like auxins and cytokinins, regulate cell division and elongation. Amino acids are crucial for protein synthesis in actively growing tissues. Signaling molecules facilitate communication between different plant parts. The phloem’s role extends beyond nutrient distribution, actively participating in the systemic coordination of various plant functions by transporting a diverse array of substances to specific target sites.
