 (a) Illustrate by means of a diagram (4"x4") your conception of the wheat flower during 

 the process of fertilization. Indicate in the diagram the following parts: ovary, style, stigma,

 tists that the ovary of a wheat flower is naturally fertilized only by pollen from stamens 

 in the same flower, (b) In a ripe head of wheat can you find any remnants of the essential
