Read the following statements:
I. Eukaryotic cell walls contain peptidoglycans in addition to cellulose.
II. Plasmodesmata and centrioles are found in all plant cells.
III. Plant cell contains 80s ribosomes which they use to manufacture proteins.
Iv. Amyloplasts are a type of plastids found in a plant cell that help so store carbohydrates.
Identify the statements that are INCORRECT regarding plant cell.

Options

A. I and II only
B. I,II III and IV
C. II and IV only
D. I and III only

Answer

To solve the question, we need to analyze each of the four statements regarding plant cells and identify which ones are incorrect.

### Step-by-Step Solution:

1. **Evaluate Statement I**:
- **Statement**: "Eukaryotic cell walls contain peptidoglycans in addition to cellulose."
- **Analysis**: This statement is incorrect. Eukaryotic plant cell walls primarily consist of cellulose. Peptidoglycan is found in the cell walls of prokaryotes, particularly bacteria, not in eukaryotic plant cells.

2. **Evaluate Statement II**:
- **Statement**: "Plasmodesmata and centrioles are found in all plant cells."
- **Analysis**: This statement is also incorrect. Plasmodesmata are indeed present in plant cells, allowing communication between them. However, centrioles are not found in all plant cells; they are typically absent in higher plant cells.

3. **Evaluate Statement III**:
- **Statement**: "Plant cells contain 80s ribosomes which they use to manufacture proteins."
- **Analysis**: This statement is correct. Plant cells contain 80S ribosomes (composed of 60S and 40S subunits) that are involved in protein synthesis.

4. **Evaluate Statement IV**:
- **Statement**: "Amyloplasts are a type of plastids found in a plant cell that help to store carbohydrates."
- **Analysis**: This statement is correct. Amyloplasts are indeed plastids that store starch, a carbohydrate, in plant cells.

### Conclusion:
- The incorrect statements are **I** and **II**. Therefore, the answer to the question is that statements I and II are incorrect regarding plant cells.

### Final Answer:
The statements that are INCORRECT regarding plant cells are **I and II**.
