Phloem is a vascular tissue in plants responsible for transporting sugars and other organic compounds from the leaves to other parts of the plant. It is not an organ itself, but rather a part of the plant's vascular system along with xylem.
The green organ in plants is called a chloroplast. It is responsible for photosynthesis, the process by which plants convert sunlight into energy.
