Which of the following plant cell is not surrounded by cell wall?

Options

A. Root hair cell
B. Stem hair cell
C. Gamete cell
D. Bacterial cell

Answer

To determine which plant cell is not surrounded by a cell wall, we can analyze the options provided:

1. **Root Hair Cells**:
- Root hair cells are extensions of root epidermal cells. They are specialized for water and nutrient absorption and are surrounded by a cell wall.

2. **Stem Hair Cells**:
- Stem hair cells (trichomes) are found on the stems of plants and serve various functions, including protection and reducing water loss. They also have a cell wall.

3. **Gamete Cells**:
- In higher plants, gametes refer to the male and female reproductive cells. The male gamete is the pollen grain, and the female gamete is the ovule. These gametes do not have a cell wall, as they are designed to fuse during fertilization.

4. **Bacterial Cells**:
- Bacterial cells are prokaryotic and have a cell wall made of peptidoglycan. However, they are not plant cells.

Based on this analysis, the correct answer is that the **gamete cells** are not surrounded by a cell wall.

### Step-by-Step Solution:
1. Identify the types of cells listed in the options: root hair cells, stem hair cells, gamete cells, and bacterial cells.
2. Analyze each cell type:
- **Root Hair Cells**: Surrounded by a cell wall.
- **Stem Hair Cells**: Surrounded by a cell wall.
- **Gamete Cells**: Do not have a cell wall.
- **Bacterial Cells**: Have a cell wall but are not plant cells.
3. Conclude that the only type of cell listed that is not surrounded by a cell wall is the **gamete cells**.
