Question

which of the following plant material is an efficient water imbibant.
a)agar
b) cellulose
c)lignin
d)pectin​

Answer 1

Answer:

Agar

Explanation:

Agar is an efficient water imbibant as it is a component made up of subunits of sugar galactose. When it is dissolved in boiling water and cooled, it looks like a gel and is often used to solidify the culture medium as it cannot be degraded by bacteria.  

Thus, the correct answer is option A.

Answer 2

Answer:

a) Agar is the correct answer

Explanation:

Agar is very hydrophilic and on heating its solution it swells up. Cellulose, lignin and pectin absorb less water by imbibition than agar.
