Question

write a short note on Xylem and phlpem

Answer 1

Xylem (transport water in plants) 
* Thick secondary cell walls, often deposited unevenly in a coil-like pattern so that they may stretch 
* Dead at functionally maturity. 
* Involved in conduct of water and ions in the plant 
* Two types - tracheids and vessels 

Phloem (transport food in form of sugars +) 
* Involved in transport of sucrose, other organic compounds, and some ions 
* Living at functional maturity 
o Protoplast may lack organelles and nucleus, though 
* Endwalls connect to each other via sieve-plates 

Answer 2

Xylem tissue is used mostly for transporting water from roots to stems and leaves but also transports other dissolved compounds.

Phloem is responsible for transporting food produced from photosynthesis from leaves to non-photosynthesizing parts of a plant such as roots and stems.
