Select the wrong statement with respect to the structure of a plant cell.

Options

A. Cellulosic cell wall is present inside the cell membrane.
B. Centrioles are usually absent.
C. A large central vacuole is present
D. Golgi apparatus is formed of a number of unconnected units called dictyosomes.

Explanation

To determine the wrong statement regarding the structure of a plant cell, we need to analyze each option provided:

1. **Option A: Cellulosic cell wall is present inside the cell membrane.**
- This statement is incorrect. In plant cells, the cell wall is located outside the plasma membrane, not inside it. The cell wall is a rigid structure made of cellulose that provides support and protection to the cell.

2. **Option B: Centrioles are usually absent.**
- This statement is correct. Plant cells typically do not have centrioles, which are found in animal cells and are involved in cell division.

3. **Option C: A large central vacuole is present.**
- This statement is also correct. Most mature plant cells contain a large central vacuole that stores nutrients and waste products and helps maintain turgor pressure.

4. **Option D: Golgi apparatus is formed of a number of unconnected units called Dictyosomes.**
- This statement is correct as well. In plant cells, the Golgi apparatus is made up of multiple smaller units called Dictyosomes, which are not interconnected like the single complex Golgi apparatus found in animal cells.

Based on the analysis, the wrong statement is:

**Final Answer: Option A - Cellulosic cell wall is present inside the cell membrane.**
