★Phloem

Phloem 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.

★Functions of phloem :

• Transports food and other nutrients including sugar and amino acids from leaves to storage organs and growing parts of the plant.
• Transports food and other nutrients including sugar and amino acids from leaves to storage organs and growing parts of the plant.Translocates the synthesized sugars by the photosynthetic areas of plants to storage organs like roots, bulbs and tubers.
• Transports food and other nutrients including sugar and amino acids from leaves to storage organs and growing parts of the plant.Translocates the synthesized sugars by the photosynthetic areas of plants to storage organs like roots, bulbs and tubers.It is responsible for transporting proteins and mRNAs throughout the plant.

Ø  Phloem is a complex tissue, composed of FOUR types of cells (phloem elements)

★The components of phloem are:

• Sieve element
• Companion cell
• Phloem parenchyma
• Phloem fibres and Sclereids
