Question

What are the different types of elements found in xylem?

Answer 1

$\bold{\huge{\underline{\underline\red{ANSWER: }}}}$

Xylem consists of four typed of cells called as elements.

$\implies$Tracheids

$\implies$Vessels

$\implies$Xylem Parenchyma

$\implies$Xylem Sclerencyma

$\mathcal{\huge{\fbox{\purple{Tracheids}}}}$

$\longrightarrow$They are elongated angular dead cells (primitive elements).

$\longrightarrow$Involved in conduction of water and minerals in gynosperms.

$\mathcal{\huge{\fbox{\pink{Vessels}}}}$

$\longrightarrow$They are advanced elements.

$\longrightarrow$It is cylindrical tube like structures placed on above the other end to end which form continuous channel for conduction of water.

$\mathcal{\huge{\fbox{\purple{Parenchyma}}}}$

$\longrightarrow$They are small and thick walled parenchymatous cells subjected for storage of starch(food)

$\longrightarrow$Only living xylem cells.

$\mathcal{\huge{\fbox{\pink{Sclerencyma}}}}$

$\longrightarrow$They are non - living fibres with thick walls

$\longrightarrow$Narrow cavities provide mechanical support.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

❥ Xylem is composed of 4 elements: tracheids, vessels, xylem parenchyma and xylem fibres.The xylem consists of tracheary elements, xylem parenchyma cells, and xylem fiber cells. Tracheary elements are dead, hollow cells with patterned cell walls comprising xylem vessels and tracheids, which function as conductive hollow tubes for water and nutrient transport throughout the plant body.
