Question

8. Write differences between : (i) Transportation in xylem and phloem?​

Answer 1

Answer:

# xylem transports water and minerals from root to other parts while phloem transports foot materials like sucrose and amino acids from site of synthesis that is leaf to other parts of the plant.

# transportation in xylem is uni directional while transportation in phloem is two way.

#Transport in the xylem requires physical forces such as transpiration pull. Transport of food in phloem requires energy in the form of ATP.

hope it helps ❤️

Answer 2

Xylem is a conducting tissue that is responsible for the transport of water while phloem is a conducting tissue that is responsible for the transport of food in plants.

Difference between xylem and phloem

$\huge\underline{\overline{\mid{\bold{\orange{xylem}}\mid}}}$

⇒Xylem transports soluble minerals and water molecules

⇒Water is absorbed by the roots and is transported to the aerial parts of the plant like the stem and leaves.

⇒Xylem tissues are composed mainly of dead cells.

⇒Transportation in the xylem is unidirectional from roots to leaves

⇒Xylem provides mechanical strength to the plant.

⇒Xylem is responsible for the amount of water loss through transpiration and photosynthesis.

$\huge\underline{\overline{\mid{\bold{\orange{Phloem}}\mid}}}$

⇒Phloem transports food and other nutrients like sugar and amino acids.

⇒Food is formed in the leaves from where it is transported to the storage organs and the growing parts of the plants.

⇒Phloem tissues are mainly composed of living cells.

⇒Phloem transportation is bidirectional from leaves to various plant parts

⇒Phloem transports the sugar in the storage organs.

⇒Phloem is responsible for transporting proteins and mRNAs throughout the plant.

⇒Phloem consists of sieve tubes, companion cells, parenchyma, fibers.
