Detailed explanation-1: -Phloem, also called bast, is a vascular tissue that runs through all the organs of plants. It transports sugars formed in the leaves during photosynthesis.

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.

Detailed explanation-3: -Phloem is the vascular tissue that transports carbon (photosynthates) from the leaves to basal parts of the plant, and vascular cambium is undifferentiated tissue responsible for secondary growth and repair of damaged phloem (Lalonde et al., 2004).

Detailed explanation-4: -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.

Detailed explanation-5: -The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.
