Question

Difference between xylem phloem​

Answer 1

Xylem - Xylem is the complex tissue of plants, responsible for transporting water and other nutrients to the plants. Xylem consists of dead cells (parenchyma is the only living cells present in the xylem).

Phloem - Phloem is living tissue, responsible for transporting food and other organic materials.

$\colorbox{yellow}{Xylem :}$

• Xylem is one of the two types of transport tissue in vascular plants, phloem being the other.
• The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients.
• Xylem can be found: in vascular bundles, present in non-woody plants and non-woody parts of woody plants.
• In secondary xylem, laid down by a meristem called the vascular cambium in woody plants.
• As part of a stelar arrangement not divided into bundles, as in many ferns.

$\colorbox{yellow}{Phloem :}$

• 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.
• Unlike xylem (which is composed primarily of dead cells), the phloem is composed of still-living cells that transport sap.
• The sap is a water-based solution, but rich in sugars made by photosynthesis.
• Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant.
