Complete the table using a tick (√) to show that the group of living organisms shows the feature and a cross (X) if the feature is absent. Some have been completed for you. Name another type of pathogen. (ii) Give an example of a disease that is caused by a protoctist.

Here are the solutions to the questions: 1. (a) Complete the table using a tick (✓) to show that the group of living organisms shows the feature and a cross (X) if the feature is absent. Bacteria: Cell wall: Present (✓) - Bacteria have cell walls. Plasmid: Present (✓) - Many bacteria contain plasmids. Cytoplasm: Present (✓) - All cells have cytoplasm. Nucleus: Absent (X) - Bacteria are prokaryotes and lack a true nucleus. Fungi: Cell wall: Present (✓) - Fungi have cell walls (made of chitin). Plasmid: Absent (X) - Fungi do not typically have plasmids. Cytoplasm: Present (✓) - All cells have cytoplasm. Nucleus: Present (✓) - Fungi are eukaryotes and have a true nucleus. Protoctists: Cell wall: Absent (X) - While some protoctists (like algae) have cell walls, many (like protozoa) do not. The table indicates a general absence for the group. Plasmid: Absent (X) - Protoctists do not typically have plasmids. Cytoplasm: Present (✓) - All cells have cytoplasm. Nucleus: Present (✓) - Protoctists are eukaryotes and have a true nucleus. Here is the completed table: | Group of organisms | Feature | | | | | :----------------- | :--------- | :--------- | :-------- | :------ | | | cell wall | plasmid | cytoplasm | nucleus | | bacteria | ✓ | ✓ | ✓ | X | | fungi | ✓ | X | ✓ | ✓ | | protoctists | X | X | ✓ | ✓ | 1. (b) Some bacteria, fungi and protoctists are pathogens. 1. (b) (i) Name another type of pathogen. Your answer: parasitic worm ✅ Correct. Other examples include viruses. Another type of pathogen is a virus. 1. (b) (ii) Give an example of a disease that is caused by a protoctist. Your answer: Malaria ✅ Correct. Malaria is caused by the protoctist Plasmodium. An example of a disease caused by a protoctist is Malaria. What's next?
