Hmmmm.... I did a search but didn't find anything. I tried looking up "roma tomato" for a good photo, and all I got was the product, not the plant!
I've grown romas, better boys and cherry tomoatoes so long - I can tell by the smell of the leaf what they are. My new friend up here thought I was nuts in the head when I sniffed a couple of seedlings, handed her Romas and Better Boys and told her which was which. Now she knows... I was right! lol.
I kinda think the cherry leaves are a little longer, if I can recall (wish I had some growing, I'd just run outside with a camera!). You can also tell by growth habit - determinate, indeterminate, bushy or tall.
I did find this really cool nutritional chart on tomatoes tho:
If you go to Google, click on "Images" near the top, and type in tomato plants, then click search, you will get several photos of different tomato plants. There may be what you are looking for in there.
Let us know, so we can keep looking if not.
