Phloem (/ˈfloʊ. əm/, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to parts of the plant where needed. This transport process is called translocation.

Photosynthates (mainly sucrose) move from sources to sinks through the plant’s phloem. Sucrose is actively loaded into the sieve-tube elements of the phloem. The increased solute concentration causes water to move by osmosis from the xylem into the phloem.

In plants, minerals and water are transported through the xylem cells from soil to the leaves. The xylem cells of the stem, roots, and leaves are interconnected forming a conducting channel reaching all plant parts.

Transpiration plays a vital role in the body of the plants, some of them are : It helps it to transport water and minerals towards the leaves from the roots in the upward direction against the gravitational pull. Continuous evaporation from stomata of leaves creates suction which pulls up water through xylem vessels .

The transport of food from the leaves to the other parts of the plant occurs through the vascular tissue called phloem. The food (sugar) made in leaves is loaded into the sieve tubes of phloem tissue by using the energy derived from ATP.

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Transpiration also cools plants, changes osmotic pressure of cells, and enables mass flow of mineral nutrients and water from roots to shoots.

The food which is prepared by the process of photosynthesis in the leaves of a plant has to be transported to other parts like stem, roots, branches etc. Therefore this food is transported to other parts of the plant through a kind of tubes called phloem. Phloem is present in all the parts of a plant.

Phloem is living tissue, responsible for transporting food and other organic materials. Xylem consists of dead cells (parenchyma is the only living cells present in the xylem).

Phloem is the vascular tissue in charge of transport and distribution of the organic nutrients. The phloem is also a pathway to signaling molecules and has a structural function in the plant body. It is typically composed of three cell types: sieve elements, parenchyma, and sclerenchyma.

Phloem consists of living cells. The cells that make up the phloem are adapted to their function: Each sieve tube has a perforated end so its cytoplasm connects one cell to the next.

Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells.

Living elements of phloem are sieve tubes, companion cells and phloem parenchyma.

The phloem is composed of sieve tubes, companion cells, phloem parenchyma and fibres. The fibres are the dead sclerenchymatous cells in the phloem responsible for mechanical support. These cells are considered as non-living component of phloem. Was this answer helpful?
