I want a drawing of corn and its plant in the style of an old explanatory sketch

I want a drawing of corn and its plant in the style of an old explanatory sketch, on a sheet of paper. The drawing must include all the elements of the plant: estate, Stems, leaves, flowers and fruits. It is important that the style is detailed and realistic, as if it were part of a field notebook.The drawing should be in soft and natural tones, avoiding strong colors. Colors should be subtle, similar to those that might have been used in old illustrations, with a palette of greens, brown and cream tones. Illustrations must include anatomical details, as cross sections of fruits and seeds. This explanation was more than enough and very good. I would also like cuts inside the fruit or plant and the entire plant must be colorful but with soft tonal colors..

worst quality, low quality, bad anatomy, bad hands, bad body, missing fingers, extra digit, fewer digits
