An amino group and carboxylic acid group are the most basic common components in all amino acids. While, R group in the amino acids always different (here R describes the alkyl group).
Organic substances having both amino and carboxylic acid functional groups are known as Amino acids. Alpha-amino acids, which make up proteins, are by far the most significant of the hundreds of amino acids found in nature.
Amino acids perform a variety of processes in our body including muscular growth, delivering nutrition, prevent disease, and many more. A lack of certain amino acids can lead to a variety of health concerns, including lowered immunity, digestive disorders, depression, less mental alertness, slower child growth, etc.

Explanation: Most Archaeas don't have membrane-bound organelles, they are mostly unicellular prokaryotic organisms.
Archaea are found living alongside bacteria in many environments. Recently Archaea belongs to Crenarchaeota have been implicated in nitrogen cycling in the soil.
Fungi are eukaryotic multicellular organisms and they have membrane-bound organelles. they are hence more closely related to plants and animals than to bacteria or archaea. Like eukaryotes, Fungi has nuclei with chromosomes that contain DNA. They possess membrane-bound organelles such as mitochondria. Fungi are heterotrophs, and they are saprophytic, they feed on decaying matter. some fungi occur as unicellular organisms, they are generally referred to as yeasts.
