Minor php customization

In the drop-down store menu (Products, Shopping Cart, Order Status) I wan to change "Products" to read "Plants" as a customization, and also, in the .../store/products page, I want the h2 header to say "Plants", too, not "Products". I was able to do this before in the marketpress.php when I was using Lite but can't find the exact place now that I have upgraded. Can you help pinpoint where in the marketress.php I can find these 2 instances?

Thanks, Your help much appreciated.
