Phloem is the vascular tissue in plants responsible for transporting sugars (primarily sucrose), produced during photosynthesis, from the leaves (source) to other parts of the plant (sink) where they are needed for growth or storage.

Xylem transports water and minerals from the roots upwards. Phloem transports organic nutrients, mainly sugars, throughout the plant. Phloem is a complex tissue made of sieve elements, companion cells, phloem parenchyma, and phloem fibres.

Simple tissues are composed of only one type of cell (e.g., parenchyma, collenchyma, sclerenchyma). Phloem, like xylem, is a complex tissue. Support in plants is primarily provided by sclerenchyma and collenchyma tissues.
