Plants can synthesize all twenty amino acids. Humans must eat plants or animals to obtain some of these amino acids.
Explanation
Plants have the capability to synthesize all twenty amino acids necessary for protein synthesis. However, humans cannot synthesize some of these amino acids and must obtain them through their diet. Specifically, humans need to ingest essential amino acids, which are amino acids that the body cannot synthesize on its own. This determines the fundamental difference between how plants and humans manage their amino acid synthesis and dietary requirements.
