I'm doing a biology project and need to know the names of these plants The flowers in picture 2 belong to the plant in picture 1
#4 looks like an Aroid of some sort. Maybe Amorphophallus konjac? Of course, I could be right off the deep end, and it could be celery or similar. Are all of the leaflets originating at one point, or is there space between them? I can't tell from that pic. #10 is a thistle; my guess would be Onopordum - it's a common weed.
#1-2 Campanula / Adenophora ? #3 Stellaria media ? #5 Chenopodium album #7 Aesculus sp. ? #8 Malva neglecta #9 Lactuca serriola
If you had the odd blossoms and the plant doesn't produce more that just that one big leaf, you've got Amorphophallus of some sort; likely A. konjac given your location.
