I've never seen a plant that didn't have at least some of all of them. Ask her which ones don't.
The human body can make its own L-carnitine, by biochemically-combining 2 other amino acids: lysine and methionine (both of which are supplied by plants): https://en.wikipedia.org/wiki/CarnitineWhat about things like l-carnitine?
There may be certain amino acids that only meat contains. However, humans only need to consume 9 of the amino acids (https://en.wikipedia.org/wiki/Essential_amino_acid), and all 9 of these are available from plant foods. (I was mistaken before, when I stated that there only 8 essential amino acids)I still believed that there were amino acids that only meat contained, but that humans could formulate from a balanced diet!
