Which statement best distinguishes plants and animals as they relate to amino acids? plants can synthesize all twenty amino acids. humans must eat plants or animals to obtain twenty of these amino acids. plants can synthesize all twenty amino acids. humans must eat plants to obtain twelve of these amino acids. plants can only synthesize ten amino acids. humans synthesize the other ten amino acids. plants and humans both synthesize all twenty amino acids. humans must supplement a few of these by eating plants..

Ans.  

Amino acids are building blocks of proteins. There are total 20 amino acids that make proteins, known as proteogenic amino acids.

Plants can synthesize all these twenty amino acids, while humans cannot make all amino acids by their own. Amino acids that cannot be synthesized by humans are known as essential amino acids. They must consume animal or plant products to obtain these amino acids.

Thus, the correct answer is option). 'plants can make all twenty proteogenic amino acids, but humans need to eat animals or plants to obtain all twenty of these amino acids.'

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
