DENDROLOGY

Detailed explanation-1: -Phloem, the vascular tissue responsible for transporting organic nutrients around the plant body, carries dissolved sugars from the leaves (their site of production) or storage sites to other parts of the plant that require nutrients.

Detailed explanation-2: -Phloem is a highly specialised vascular tissue that forms an interconnected network of continuous strands throughout a plant’s body. It transports sugars, nutrients, and a range of signalling molecules between leaves, roots, flowers, and fruits. As a result, phloem is central to plant function.

Detailed explanation-3: -Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks.

Detailed explanation-4: -In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), particularly sucrose; a sugar, to all parts of the plant.
