Create a biology concept chart (graph) connecting these terms: amino acid, sugar, nucleotide, carbohydrate, lipid, nucleic acid, RNA, enzyme, glucose, phospholipid, cholesterol, DNA, hydrogen, carbon, nitrogen, oxygen, cell membrane, fatty acid, monomer, polymer.

What you are building

You want a single map that shows:

• Elements ($C$, $H$, $O$, $N$) that make up biological molecules
• Monomers (building blocks)
• Polymers/macromolecules (made from monomers)
• A key structure (cell membrane) built from specific lipids

Concept chart (Mermaid graph)

Paste this into a Mermaid live editor (or any Mermaid-enabled notes app):

How to read the chart

• Monomer → Polymer: sugars (like glucose) form carbohydrates, and nucleotides form nucleic acids.
• DNA and RNA are both nucleic acids, so they branch off from that category.
• Enzymes are a type of protein, and proteins are built from amino acids.
• The cell membrane is made largely of phospholipids (a lipid) plus cholesterol.
• Carbon, hydrogen, oxygen, nitrogen connect to “biomolecules” to show they are common elements in these molecules.

Quick tweak options

• If your teacher wants “protein” explicitly in the word bank, you can keep it; if not, remove the “Protein” node and connect amino acid → enzyme directly, but that is less accurate biologically.
