the parts which are not present in an animal cell is
A. cell membrane B. chloroplasts C. cell wall D. mitochondria

Options

A. A nd B
B. B and C
C. Aand d
D. B and D

Answer

To determine which parts are not present in an animal cell, let's analyze each option provided in the question:

**Step 1: Understand the components of an animal cell.**
An animal cell is a type of eukaryotic cell that has a complex structure. It contains various organelles, but it lacks certain structures that are found in plant cells.

**Step 2: Analyze the options given.**
- **A. Cell membrane**: This is present in animal cells. It acts as a barrier that separates the interior of the cell from the external environment.
- **B. Chloroplasts**: These are not present in animal cells. Chloroplasts are the organelles responsible for photosynthesis, which allows plants to make their own food.
- **C. Cell wall**: This is also not present in animal cells. The cell wall is a rigid outer layer found in plant cells that provides structure and support.
- **D. Mitochondria**: These are present in animal cells. Mitochondria are known as the powerhouses of the cell because they produce energy (ATP) through cellular respiration.

**Step 3: Identify the correct answer.**
From the analysis above, both chloroplasts and cell walls are not present in animal cells. However, since the question asks for the parts which are not present, we need to choose one option. The best answer is **B. Chloroplasts**, as they are specifically associated with the ability to produce food, which animal cells cannot do.

**Final Answer: B. Chloroplasts**
