Assertion :- Long distance transport of substances within plant cannot be by diffusion alone.
Reason:- Diffusion is a slow process

Why should there be a long distance transport system in plants?

Assertion :- For small distance transportation of substances there is no need of vascular tissue. Reason:- Over small distance substances move by diffusion and cytoplasmic streaming

Long distance bulk transport of substance through conducting or vascular tissue is called as

Assertion: Digesetd material is absorbed in the intestine through the process of diffusion. Reason: Diffusion is a very fast process of absorption.

Assertion :- During diffusion of substances there is no energy expenditure. Reason:- Diffusion takes place according to concentration gradient

List out the substances that are transported by facilitated diffusion.

Explain why, the diffusion of a solid in another solid is a very slow process.
