Worked Solution & Example Answer:Plant cells and fungal cells are similar in structure - AQA - GCSE Biology - Question 8 - 2010 - Paper 1
Step 1
08.1 Name one structure in Figure 10 which is present in both plant cells and fungal cells but not in animal cells.
Answer
One structure that is present in both plant cells and fungal cells, but not in animal cells, is the cell wall. The cell wall provides structural support and protection.
Step 2
Step 3
08.3 A fungal cell divides once every 90 minutes. How many times would this fungal cell divide in 24 hours?
Answer
To calculate how many times the fungal cell divides in 24 hours, we first need to determine the total number of minutes in 24 hours:
Now we divide that by the time it takes for one division:
Thus, the fungal cell would divide 16 times in 24 hours.

08.6 Evaluate the use of burgers made from meat compared with meat-free burgers in providing humans with a healthy, balanced diet.
Answer
When evaluating burgers made from meat versus meat-free burgers, several nutritional aspects must be considered:
Meat Burgers
- Higher Protein Content: Meat burgers contain approximately 14.0 g of protein per 100 g, which is beneficial for muscle growth and repair.
- Higher Fat and Cholesterol: They also have more fat (16.0 g) and cholesterol (120 mg), which can lead to health issues such as heart disease if consumed excessively.
Meat-Free Burgers
- Higher Fiber Content: Meat-free burgers, on the other hand, provide more fiber (5.5 g), promoting digestive health and aiding in preventing constipation.
- Lower in Fats: With only 5.2 g of fat, these burgers are generally lower in unhealthy fats, which is beneficial for heart health.
Conclusion
In summary, while meat burgers offer higher protein content crucial for growth, meat-free burgers are healthier due to their lower fat content and higher fiber. For a balanced diet, incorporating a variety of protein sources and being mindful of fat and cholesterol intake is essential. Therefore, a mix of both types of burgers could help create a well-rounded diet.
