Will you please tell me how xylem and phloem develop in a plant and how new ones are formed?

Sandra said: (Oct 22, 2012)  
Xylem and pholm are develop in process of growth. Primary growth is the first and older part of the stem that is thin, Then secondary growth comes to help support the steam in width as lateral emp that also has a 2nd xylem and phlom.

What is provascular tissue?

Jayasree said: (Dec 24, 2013)  
Phloem gives food nutrients to plants. Due to this the vascular tissue well developed.

What is provascular tissue?

Yasir said: (Apr 16, 2014)  
Cell in the primary plant body that later differentiate into xylem, phloem, or vascular cambium.

Provascular tissue?

Dhruvil said: (Jun 23, 2014)  
Primary phloem develops from provascular tissues like phloem parenchyma containing sieve tubes and companion cells which provide food supplements to various parts of plants.

What is provascular tissue ?

Anu said: (Dec 27, 2014)  
It is also known as procambium, a plant tissue formed by apical meristem of root and shoots.

Rupesh said: (Apr 23, 2015)  
Food is pass through by phloem tissue.

What is epical meristem?

Ruweida said: (Aug 11, 2015)  
Apical meristem is a meristem at the tip of plant shoot or root that produces auxin and causes the shoot or root to increase in length. Growth originates from apical meristem is known as primary growth.

Dave said: (Feb 21, 2016)  
Wow! thanks for the idea about meristem.

Raj said: (Aug 27, 2016)  
What is meristem?

Vathsalya said: (Dec 12, 2016)  
What is meant by primary phloem and pro-vascular tissue?

Rajesh Katkar said: (Feb 1, 2017)  
The cells of Phloem tissues are generally living hence they have the capacity to devide and give rise to new phloem tissues, simply know as provascular tissue.

Rakshith said: (Jun 30, 2017)  
What is extrastelar cambium what is the function of it?

Narayan said: (Jul 18, 2017)  
What is pro-vascular tissue?

Mudasir Habib said: (Mar 11, 2018)  
What is mean by it?

Tani said: (Apr 3, 2019)  
Provascular tissue is an embryonic tissue located in the vascular cylinder. Although this provascular meristem doesnot directly give xylem or phloem. It produces precursor cells that will give rise to xylem and phloem.
