As compared to plant cells, animal cells are found in a variety of shapes. Animal cells are found in a verity of shapes because of the presence of a flexible

Options

A. vacuole
B. nucleus
C. cell wall
D. cell membrane

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks why animal cells are found in a variety of shapes compared to plant cells. This implies that there is a structural difference between the two types of cells that allows for this variability.

2. **Identifying the Key Structures**: To answer this question, we need to consider the key structures present in animal and plant cells. The main structures to focus on are the cell wall, cell membrane, vacuoles, and nucleus.

3. **Analyzing Each Option**:
- **Option 1: Vacuole**: Vacuoles are large in plant cells and help maintain their shape and rigidity. In animal cells, vacuoles are smaller and not responsible for shape variability. Thus, this option is incorrect.
- **Option 2: Nucleus**: The nucleus is present in both plant and animal cells and is involved in regulating cellular activities. It does not contribute to the shape of the cell. Therefore, this option is also incorrect.
- **Option 3: Cell Wall**: Plant cells have a rigid cell wall that provides structure and support. Animal cells do not have a cell wall, which allows them to adopt various shapes. This option is incorrect as it does not apply to animal cells.
- **Option 4: Cell Membrane**: Animal cells have a flexible cell membrane that allows them to change shape easily. This flexibility is the reason animal cells can take on various forms.

4. **Conclusion**: The correct answer is that animal cells are found in a variety of shapes because of the presence of a flexible **cell membrane**.

### Final Answer:
Animal cells are found in a variety of shapes because of the presence of a flexible **cell membrane**.
