Assertion. Plant cell wall lacks selective permeability.
Reason. It allows free passage of dissolved materials through it.

These questions consist of two statements each,printed as Assertion and Reason.While asnwering these questions you are required to chose any one of the following four responses. If both Assertion and Reason are true and Reason in correct explanation of Assertion. If both assertion and Reason are true but reason is not correct explanation of Assertion. If Assertion is true but Reason is false. If both Assertion and Reason are false. Assertion:Plant cell wall lacks selective permeability. Reason:It allows free passage of dissovled material through it.

Selective permeable membrane allow passage of

Assertion : Plasma membrane is selectively permeable. Reason : Plasma membrane allows some molecules to pass through more easily than others.

The selectively of differentially permeable membrane allows the passage of

Assertion : The S.I. unit of thermal conductivity is watt m ^(1)1 K^(1) . Reason : Thermal conductivity is a measure of ability of the material to allow the passage of heat through it.
