What substance can the sundew plant make using the nitrogen?

Nitrogen is a crucial element for plants, as it is a component of many organic molecules essential for life. - **Proteins:** Proteins are made from amino acids. Every amino acid has a central carbon atom bonded to an amine group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a variable R group. The amine group contains nitrogen, making nitrogen essential for protein synthesis. - **Nucleic Acids (DNA and RNA):** The nitrogenous bases (adenine, guanine, cytosine, thymine, uracil) in nucleotides all contain nitrogen. Of the options given, only protein is made from nitrogen-containing subunits (amino acids). Fatty acids, glucose, and lactic acid are primarily composed of carbon, hydrogen, and oxygen.
