Does root hairs contains pores to absorb water?

Kanhaiya said: (Feb 20, 2012)  
Yes, and root contain xylem which transport water from root to different part of plant. Root hair help to absorb water from soil.

Vasan said: (Mar 6, 2012)  
Yes root very impartant of plant parts which transport water from the root to various part.

Bhavana said: (May 4, 2012)  
Root is base of a plant. So it absorb most part of water needed naa. Is it right.

Avinsh said: (May 13, 2012)  
Yes they contain pores and root hairs consists of vascular tissues so root hairs so they conduct water from soil.

R.Pavani Reddy said: (Jul 27, 2012)  
Root hairs are important to plants they absorb water and nutrients through the root hairs.

B.Jayasree said: (Dec 23, 2013)  
Root hairs have pores and vascular tissues and they are elongated in the soil and absorb soil.

Vaishu said: (Dec 28, 2013)  
In general, root hairs are made up of cellulose and cellulose is hydrophilic in nature. Hydrophilic means a compound which has attraction of water. So root hair absorb water.

What is embryonic zone?

Sin said: (May 9, 2015)  
Root hairs are primary site for absorption.

Vivek Gautam said: (Jul 26, 2015)  
Yes, plants absorb most part of water needed by their root hairs because of their hydrophilic nature.

Root hair absorbs the water and transfers to xylem. So I can say, that the root hair is the most important part of the plant.

Rupsa said: (Dec 7, 2016)  
Root hair is the vital organ of root system playing an important role in absorption.

Siva Shankari said: (Mar 26, 2017)  
Most of the minerals is got from the soil and the obvious way to absorb them from the soil is by the root hairs. This occurs with help of diffusion where are the soil has more concentration of minerals compared to the root hairs. With the help of transpirational pull the mineral is utilised by other parts.

Jaanu said: (Dec 24, 2017)  
Yes, roots contain vascular bundles i.e. Xylem and Phloem in this Xylem conducts water.

Gurwinder Kaur said: (Sep 6, 2018)  
Because most of the water get absorbed by the root hairs.

Prakash said: (Apr 11, 2019)  
Root hair absorbed most of the water.
