Phloem is a complex tissue found in all vascular plants that plays a crucial role in the transport of nutrients and sugars. Composed of sieve tube elements and companion cells, this transportation network is responsible for distributing essential substances throughout the plant’s body. Unlike xylem, which transports water and minerals, phloem carries sugars produced during photosynthesis to various plant organs such as roots, stems, and leaves. As organic molecules move through sieve tubes, pressure differences and active transport mechanisms facilitate their movement. This continuous flow of nutrients ensures proper growth, development, and maintenance of plants. Understanding the intricate workings of the phloem helps us appreciate the remarkable transportation system plants have evolved to thrive in their environments.#16#
