Worked Solution & Example Answer:The protist that causes malaria is passed from one person to another person by mosquitos - AQA - GCSE Biology - Question 5 - 2023 - Paper 1
Step 1
What term describes an organism that passes a pathogen from one person to another?
Answer
The term that describes an organism that passes a pathogen from one person to another is a vector. Vectors are typically living organisms, such as insects, that transmit infectious pathogens between humans or from animals to humans.
Step 2
Figure 7 shows the malarial protist.
Answer
To describe the malarial protist shown in Figure 7, mention three characteristics:
- The protist has mitochondria, which are essential for energy production.
- The protist does not have a nucleus or its genetic material is not free in the cytoplasm.
- The protist does not have plasmids, differentiating it from other cell types.
These points highlight the unique cellular structure of malarial protists compared to other organisms.
