Which one of the following is absent in plant cell?

Options

A. Vacuole
B. Cell wall
C. Centrosome
D. Plastids

Answer

To determine which structure is absent in plant cells, we will analyze each of the given options step by step.

### Step 1: Analyze the first option - Vacuole
- Vacuoles are large, membrane-bound organelles found in plant cells. They serve various functions, including storage of nutrients, waste products, and helping maintain turgor pressure within the cell.
- **Conclusion**: Vacuoles are present in plant cells.

**Hint**: Remember that vacuoles are essential for storage and maintaining cell pressure in plants.

### Step 2: Analyze the second option - Cell Wall
- The cell wall is a rigid outer layer that surrounds the cell membrane in plant cells. It provides structural support, protection, and helps maintain the shape of the cell.
- **Conclusion**: Cell walls are characteristic features of plant cells.

**Hint**: The cell wall is crucial for the structural integrity of plant cells.

### Step 3: Analyze the third option - Centrosome
- Centrosomes are organelles that play a key role in cell division by organizing microtubules and forming spindle fibers. They are typically found in animal cells.
- **Conclusion**: Centrosomes are absent in plant cells.

**Hint**: Think about the role of centrosomes in animal cells and their absence in plant cells.

### Step 4: Analyze the fourth option - Plastids
- Plastids are organelles found in plant cells that are involved in the synthesis and storage of food. They include chloroplasts (which contain chlorophyll and are involved in photosynthesis), chromoplasts, and leucoplasts.
- **Conclusion**: Plastids are present in plant cells.

**Hint**: Plastids are vital for photosynthesis and storage in plants.

### Final Conclusion:
After analyzing all the options, the correct answer is that **centrosomes are absent in plant cells**.

**Final Answer**: Centrosome
