Design 3 types of plants - repost

Hi, I have attached a single page brochure that shows 3 plant diagrams I would like done: 1. a cross section of a seed (no micronutrients on) - this is a wheat seed - 2. a plant with roots - this is a small wheat plant - please keep the same plant but make look a bit different 3. close up of leaf - one again no little round micronutrients on The should be similar but not identical. provide as hi-res images to be placed into artwork.
