Consider the following statements:

I. In low concentrations, auxin can inhibit ethylene formation and transport of precursor

   in plants;
II. High concentrations of auxin can induce the synthesis of ethylene.

III. Therefore, the high concentration can induce maleness of flowers in some species.

The correct statements are:

(1) I, II, III

(2) I, II

(3) I, III

(4) II, III

Consider the following statements regarding the synthesis and distribution of auxins:

I. Auxins are made continuously in the shoot apex and young leaves

II. It moves away from the tip and its movement is described as basipetal and polar

III. It moves by active transport from cell to cell and is eventually inactivated and

     degraded by enzymes

IV. Long term transport can also occur via the vascular system (mainly phloem) from

    shoots to roots

V. No auxin is made by roots

The correct statements are:

(1) I, II, III1

(2) I, II, IV

(3) II, III, 2

(4) III, IV, 34
