Answer 1

Plants and bacteria can synthesize all 20 of the amino acids. Humans have to consume plants or animals for these amino acids in order to keep their body balanced. The answer is A.

Answer 2

The correct answer is the first option - Plants can synthesize all twenty amino acids. Humans must eat plants or animals to obtain twenty of these amino acids. We cannot just create these amino acids on our own the way plants can - we get them from the food we eat, which includes both animals and plants, not just one of them. This is the main difference between animals and plants when it comes to amino acids.
