Over small distances substances move by (A)____ and by (B)____ supplemented by (C)_____

Over small distances, substances moved by

" In plants,over small distances substance move by all except "

How many of the following statements are not correct? [I] In a flowering plant the substances that would need to be transported are water, mineral nutrients, organic nutrients and plant growth regulators. [II] Over small distances, substances move by diffusion and by cytoplasmic streaming supplemented only by passive transport. [III] Organic and mineral nutrients undergo multidirectional transport through the xylem. [IV] From the storage organs, organic compounds are later re-exported. [V] Phytohormones and other chemical signals are transported to maintain and regulate the plant functions.

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

Transport of substance over small distance occurs by

A tetra-atomic molecule (A) on reaction with nitrogen (I) oxide, produces two substances (B) and (C). (B) is a dehydrating agent while substance (C) is a diatomic gas which shows almost inert behaviour. The substances (A),(B) and (C) are
