Phloem Function

Phloem functions primarily in transport of sugars. The various other phloem functions are given below:

1. Phloem is primarily responsible for the transport of organic nutrients, such as sugars produced through photosynthesis, from leaves to areas of active growth or storage in the plant.
2. Phloem parenchyma cells store surplus nutrients and can redistribute them to other parts of the plant when needed. It help in maintaining the overall nutrient balance.
3. Companion cells associated with sieve tubes in the phloem provide metabolic support. It ensure the energy and resources required for efficient nutrient transport.
4. Phloem sap contains signaling molecules that can convey information over long distances within the plant. It help coordinate responses to environmental changes or stress.
5. Phloem facilitates the transport of plant hormones, such as auxins and gibberellins. It regulates various physiological processes such as growth, development, and response to environmental stimuli.
6. Some components in the phloem sap, including secondary metabolites and defensive proteins, contribute to the plant’s defense against pathogens by deterring or inhibiting the activities of herbivores or microorganisms.

The Diagram of Phloem Tissue helps us understand the structure and function of the phloem tissue. Phloem tissue is a vascular plant tissue responsible for transporting sugars, amino acids, and other organic nutrients. The labelled diagram of phloem tissue shows that it consists of sieve tube elements, companion cells, and phloem parenchyma. The phloem plays an essential role in the distribution of nutrients throughout the plant. In this article, we will learn about the phloem tissue and its structure with the help of a diagram of the phloem.
