Life Science Synthesis Processes

Name:

Date:

Learning Goal: Students will understand synthesis processes in living organisms and identify where these occur in cells.

Estimated Time: 45 minutes

🔥 Part 1: Warm-up - Synthesis vs Breakdown (5 minutes)

1. What is the main difference between synthesis and breakdown processes?

Synthesis builds complex molecules; breakdown destroys them

Synthesis uses energy; breakdown releases energy

Both A and B are correct

Only A is correct

2. Which organelle is the main site of protein synthesis?

Nucleus

Ribosomes

Mitochondria

Golgi apparatus

3. Name one example of synthesis that occurs in plant cells but not animal cells:

4. What type of synthesis occurs during photosynthesis?

5. Which process requires more energy input?

Synthesis processes

Breakdown processes

Both require the same energy

6. Give one example of where lipid synthesis occurs in cells:

🔬 Part 2: Cell Structure and Synthesis (10 minutes)

Instructions: Below are descriptions of plant and animal cell components. Select 8 parts relevant to synthesis processes and complete the table.

Available cell parts: Nucleus, Ribosomes, Rough ER, Smooth ER, Golgi apparatus, Mitochondria, Chloroplasts (plants only), Cell membrane, Cytoplasm, Vacuole, Cell wall

Label and explain the synthesis role of 8 cell parts:

1. Cell part: _________________ Role in synthesis: _________________________________

2. Cell part: _________________ Role in synthesis: _________________________________

3. Cell part: _________________ Role in synthesis: _________________________________

4. Cell part: _________________ Role in synthesis: _________________________________

5. Cell part: _________________ Role in synthesis: _________________________________

6. Cell part: _________________ Role in synthesis: _________________________________

7. Cell part: _________________ Role in synthesis: _________________________________

8. Cell part: _________________ Role in synthesis: _________________________________

⚙️ Part 3: Synthesis Scenarios (15 minutes)

Word Bank: amino acids, glucose, fatty acids, nucleotides, ATP, water, oxygen, CO₂, light energy, enzymes, proteins, carbohydrates, lipids

Scenario A: A muscle cell is building new proteins for growth and repair.

Synthesis type: _________________

3 Inputs needed: _________________, _________________, _________________

2 Outputs produced: _________________, _________________

How energy is used (2-3 sentences):

Where this occurs: _________________

Scenario B: A leaf cell is producing starch during photosynthesis.

Synthesis type: _________________

3 Inputs needed: _________________, _________________, _________________

2 Outputs produced: _________________, _________________

How energy is used (2-3 sentences):

Where this occurs: _________________

📊 Part 4: Data Interpretation (10 minutes)

Data Table: Resource Availability vs Rate of Protein Synthesis

Resource Level (%): 0, 25, 50, 75, 100

Synthesis Rate (proteins/minute): 0, 15, 35, 48, 50

Graph the data above in the space below:

1. What happens to synthesis rate as resource availability increases?

2. At what resource level does the synthesis rate begin to plateau?

3. What is the independent variable in this experiment?

4. Suggest one reason why the synthesis rate plateaus at high resource levels:

💭 Part 5: Reflection (5 minutes)

1. What part of today's lesson was easiest for you?

2. What concept about synthesis processes was most confusing?

3. Give one real-world connection to synthesis processes:
