Question

Read the following statements carefully.
(a) Under certain conditions chemically combined water is useful in the phenomenon of night recovery
(b) Term 'Apoplast' was proposed by Munch
(c) Value of imbibition pressure is 100 bars in dry pea seeds

• A. Only (a) is correct
• B. All incorrect
• C. (a) and (c) are correct
• D. Only (b) is correct

Answer 1

The correct option is D Only (b) is correct

Increase in concentration of soil will bring down the osmotic pressure that will reduce the recovery of lost water in transpiration.
Term apoplast was proposed by Munch in 1930 to separate living symplast from dead apoplast. This statement is correct.
Value of imbibition pressure is 1000 bars in dry pea seeds, not 100 bars. So, this statement is incorrect.
Hence, only statement 'b' is correct.
