I did an image search on Google for 'plant structure' & came up w/ many diff kinds...i thought it would be best to just let you look thru them & pick which ones would be the best...good luck!! :o)

Google image search is quite good as nature_girl says.

Try several searches. For the older group flower structure might pull up a lot of good stuff. Plant drawings pulls up some interesting stuff. Tree anatomy is interesting.

You may already know this but clicking on the picture will separate it out from the many pictures and then clicking on the picture again will sometimes, not always, make it much larger. These last two clicks may be rather slow on some computers.

We found a bunch of printouts for grades k-3 on the enchanted learning website. Our son used several of these for his report on owls. Hope this helps. CAS

everything you could ever want to know about plant processes can be found in books about Hydroponics. go to your local library and search for hydroponics, to understand why it works you have to know about plant systems and nutrient uptake and processing.

Marie, try this link. It is a database of old (1901 to 1905) illustrations of various plants, listed by their botanical names. These illustrations were made by Carl Lindeman (from Sweden) and are in his "C.A.M.Lindeman's Flora" They are absolutely stunning images and very detailed. For instance, the first on the list, Maple (Acer) show the seeds, leaves, flowers, etc. I hope these are of some help to you.
