Xylem and Phloem are the vascular tissues that transport the food, minerals and water within the plant. Xylem transport the water and minerals while Phloem transport food and nutrients. The movements in Xylem is unidirectional from roots to aerial parts while the movements in Phloem are bidirectional.
Xylem is the vascular plant tissues. They are important for the vascular system. They transport water and minerals from the roots of the plant to the aerial parts. The flow of water and nutrient is unidirectional from roots to upwards. Xylem makes vascular bundles with phloem for mechanical strength. It contains dead tissues at maturity with no cell contents. Xylem has two tracheids and vessels for conducting the water and minerals.
Phloem are the vascular Plant tissues. they are important for the vascular system. They transport food and nutrients from leaves to the other growing and supporting parts of plants. The flow of food and nutrients is bidirectional. Phloem makes vascular bundles with xylem for mechanical strength. It contains living tissues without a nucleus. Phloem has sieve tubes for conducting food and nutrients.
Key Differences between Xylem and Phloem
- Xylem transport the water and minerals while Phloem transport food and nutrients
- The movements in Xylem is unidirectional from roots to aerial parts while the movements in Phloem are bidirectional.
- Xylem tissues have star shape while phloem is not star-shaped.
- Phloem occurs on the outer side of the vascular bundle while xylem is at the centre of the vascular bundle
- Conducting cells in Xylem are dead while conducting cell in phloem are living.
- Xylem tissues provide mechanical strength while phloem tissues don’t have mechanical strength.
- Xylem has lignin in its wall while phloem doesn’t have lignin in its wall.
- Conducting elements in xylem are two types i.e. tracheids and vessels while conducting elements in phloem is of one type i.e. sieve tube.
