Detailed explanation-1: -Photosynthates, such as sucrose, are produced in the mesophyll cells (a type of parenchyma cell) of photosynthesizing leaves. Sugars are actively transported from source cells into the sieve-tube companion cells, which are associated with the sieve-tube elements in the vascular bundles.

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: -The plant’s phloem transports the dissolved sugars from the leaves and takes them to various storage sites throughout the plants, like roots or tubers, known as “sinks”. The phloem off-loads its sugary cargo to these sinks across cell membranes through a process known as active transport.

Detailed explanation-4: -Sugars are moved about the plant in a layer of cells called the phloem. Phloem is made up of living cells located just outside the cambium. The cambium produces the phloem in trunks, branches and roots.

Detailed explanation-5: -Phloem: Phloem is a type of permanent tissue present in plants. It helps in the conduction of food in plants. Plants synthesise their food in the form of glucose which is transported by phloem to different parts of the plant.
