Concept map worksheet designed to help Biology 10 students categorize the four main types of biomolecules and their building blocks.

Absolutely! Let’s solve the diagram by filling in the missing blanks based on biological knowledge of biomolecules. The goal is to correctly match each macromolecule (Carbohydrates, Lipids, Proteins, Nucleic Acids) with its monomer and examples.

🔬 Key Concepts Recap:

1. Carbohydrates
- Monomer: Monosaccharide (e.g., glucose, fructose)
- Examples: Starch (plant storage), cellulose, glycogen

2. Lipids
- Not made of repeating monomers like polymers, but often built from fatty acids and glycerol.
- Examples: Oil, butter, phospholipids, waxes
- *Note: Sometimes “fatty acid” is listed as a building block, even though lipids aren’t true polymers.*

3. Proteins
- Monomer: Amino acids
- Examples: Eggs and meat (rich in protein), enzymes, antibodies

4. Nucleic Acids
- Monomer: Nucleotide
- Examples: DNA, RNA

✔ Filling in the Diagram:

Let’s go branch by branch.

---

#### ➤ Left Branch: Carbohydrates
- It says: “monomer → [blank]”
- → Monosaccharide
- “for example → [blank]”
- → Starch (already given in the word bank — perfect match!)

✔ So:
- Blank under “monomer” for Carbohydrates = Monosaccharide
- Blank under “for example” = Starch

---

#### ➤ Second Branch (from left): Lipids
- “such as → [blank]” — this is the category name.
- → Lipids (already in word bank)
- “monomer → [blank]” — although not true polymers, the building block is often called Fatty acid
- “for example → [blank]” — we have Oil already placed below it → so the blank above should be Fatty acid

✔ So:
- Category: Lipids
- Monomer: Fatty acid
- Example: Oil (already placed)

---

#### ➤ Third Branch: Proteins
- “such as → [blank]” → Proteins
- “monomer → [blank]” → Amino acids (given in diagram!)
- “for example → [blank]” → Eggs and meat (in word bank)

✔ So:
- Category: Proteins
- Monomer: Amino acids (already filled)
- Example: Eggs and meat

---

#### ➤ Rightmost Branch: Nucleic Acids
- “such as → [blank]” → Nucleic acids
- “monomer → [blank]” → Nucleotide
- “for example → [blank]” → DNA (already placed)

✔ So:
- Category: Nucleic acids
- Monomer: Nucleotide
- Example: DNA

🧩 Final Answer – Filled Blanks:

From left to right, the blanks in the diagram should be filled as follows:

1. Under Carbohydrates → monomer:
➤ Monosaccharide

2. Under Carbohydrates → for example:
➤ Starch

3. Top of second branch → “such as”:
➤ Lipids

4. Under Lipids → monomer:
➤ Fatty acid

5. Under Lipids → for example:
➤ *(Already has Oil — no blank needed)*

6. Top of third branch → “such as”:
➤ Proteins

7. Under Proteins → for example:
➤ Eggs and meat

8. Top of rightmost branch → “such as”:
➤ Nucleic acids

9. Under Nucleic acids → monomer:
➤ Nucleotide

📌 Summary Table for Clarity:

| Biomolecule | Monomer | Example |
|------------------|----------------|------------------|
| Carbohydrates | Monosaccharide | Starch |
| Lipids | Fatty acid | Oil |
| Proteins | Amino acids | Eggs and meat |
| Nucleic Acids | Nucleotide | DNA |
