Read the following statements and find out the incorrect statements.

Options

A. The shape of cell may vary with the function they perform.
B. The prokaryotic cell lack all membrane bound organells.
C. Scheiden, a German botanist concluded, based on his studies on plant tissues, that the presence of cell wall is a unique character of the plant cells.
D. Based on their studies on plant and animals, Schawann, a British Zoologist, proposed the hypothesis that the bodies of animals and plants are composed of cells and product of cells.

Explanation

To determine the incorrect statements from the provided information, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Statements**: Read through the statements carefully to understand what each one claims about cells, their structure, and the scientists involved.

2. **Evaluate Each Statement**:
- **Statement 1**: "The shape of the cell varies with the function they perform."
- **Evaluation**: This is correct. Cells have different shapes based on their functions (e.g., nerve cells vs. kidney cells).

- **Statement 2**: "Prokaryotic cells lack all membrane-bound organelles."
- **Evaluation**: This is also correct. Prokaryotic cells do not have membrane-bound organelles like mitochondria or lysosomes.

- **Statement 3**: "Schleiden concluded that the presence of cell wall is a unique character of the plant cell."
- **Evaluation**: This statement is incorrect. It was Schwann who proposed that the cell wall is a unique characteristic of plant cells, not Schleiden.

- **Statement 4**: "Schwann proposed the hypothesis that the bodies of animals and plants are composed of cells and products of cells."
- **Evaluation**: This statement is correct. Schwann did contribute to the cell theory.

- **Statement 5**: "Schleiden stated that all cells in animals and plants are composed of multiplication or pre-existing cells."
- **Evaluation**: This statement is incorrect. Schleiden is known for his work on plant cells, but the phrasing here is misleading regarding his contributions.

3. **Summarize the Findings**: Based on the evaluations, the incorrect statements are:
- Statement 3 (regarding the scientist who identified the cell wall as unique to plant cells)
- Statement 5 (misrepresentation of Schleiden's contributions)

4. **Conclude**: The incorrect statements are statements 3 and 5.

### Final Answer:
The incorrect statements are:
- Statement 3: "Schleiden concluded that the presence of cell wall is a unique character of the plant cell."
- Statement 5: "Schleiden stated that all cells in animals and plants are composed of multiplication or pre-existing cells."
