The correct Answer is:
To solve the question, we need to analyze each statement regarding plant cells and identify which ones are incorrect. **Step 1: Analyze Statement I** - Statement I: "Eukaryotic cell walls contain peptidoglycans in addition to cellulose." - **Analysis**: In plant cells, the cell wall is primarily composed of cellulose. Peptidoglycan is found in the cell walls of prokaryotes (like bacteria), not in eukaryotic cells. Therefore, this statement is incorrect. **Step 2: Analyze Statement II** - Statement II: "Plasmodesmata and centrioles are found in all plant cells." - **Analysis**: Plasmodesmata are indeed present in plant cells and facilitate cell-to-cell communication. However, centrioles are not found in all plant cells; they are typically absent in higher plants (angiosperms). Thus, this statement is also incorrect. **Step 3: Analyze Statement III** - Statement III: "Plant cells contain 80s ribosomes which they use to manufacture proteins." - **Analysis**: Plant cells, being eukaryotic, contain 80S ribosomes, which are involved in protein synthesis. This statement is correct. **Step 4: Analyze Statement IV** - Statement IV: "Amyloplasts are a type of plastids found in a plant cell that help to store carbohydrates." - **Analysis**: Amyloplasts are indeed a type of plastid in plant cells that store starch, a carbohydrate. This statement is correct. **Conclusion: Identify Incorrect Statements** - The incorrect statements are: - Statement I: Incorrect - Statement II: Incorrect - Statement III: Correct - Statement IV: Correct Thus, the statements that are incorrect regarding plant cells are **I and II**. ---
