The correct Answer is:
To determine how many organisms from the provided list have a cell wall at any point in their life cycle, we will analyze each organism individually. ### Step-by-Step Solution: 1. **Golden Algae (Desmids)**: - Golden algae have a cell wall made of silica and are known to have a cell wall in their vegetative form. - **Conclusion**: Has a cell wall. 2. **Euglena**: - Euglena is a unicellular organism that does not have a cell wall; instead, it has a pellicle, which is a flexible outer layer. - **Conclusion**: Does not have a cell wall. 3. **Entamoeba**: - Entamoeba is a genus of amoeboid protozoa that do not possess a cell wall. - **Conclusion**: Does not have a cell wall. 4. **Gonyaulax**: - Gonyaulax is a dinoflagellate that has a cell wall made of cellulose. - **Conclusion**: Has a cell wall. 5. **Mycoplasma**: - Mycoplasma is a type of bacteria that is known for lacking a cell wall entirely. - **Conclusion**: Does not have a cell wall. 6. **Slime Mould**: - Slime moulds can have a cell wall in their spore form, which is typically made of chitin. - **Conclusion**: Has a cell wall. 7. **Trypanosoma**: - Trypanosoma is a genus of parasitic protozoa that do not have a cell wall. - **Conclusion**: Does not have a cell wall. 8. **Sporozoa**: - Sporozoa, or Apicomplexa, are a group of parasitic protozoa that do not have a cell wall. - **Conclusion**: Does not have a cell wall. 9. **Albugo**: - Albugo is a genus of fungi, which have a cell wall made of chitin. - **Conclusion**: Has a cell wall. 10. **Paramecium**: - Paramecium is a ciliate protozoan that has a pellicle instead of a cell wall. - **Conclusion**: Does not have a cell wall. ### Final Count: From the analysis: - Organisms with a cell wall: **Golden Algae, Gonyaulax, Slime Mould, Albugo**. - Total: **4 organisms** have a cell wall at some point in their life cycle.
