Which one of the following bacterial characters is also a plant character ?
(a) Heterotrophic nutrition
(b) Prokaryotic organisation
(c) Presence of flagella
(d) Rigid cell wall

Options

A. Heterotrophic nutrition
B. Prokaryotic organisation
C. Presence of flagella
D. Rigid cell wall

Explanation

To solve the question "Which one of the following bacterial characters is also a plant character?" we will analyze each option provided:

1. **Understanding the Options:**
- (a) Heterotrophic nutrition
- (b) Prokaryotic organization
- (c) Presence of flagella
- (d) Rigid cell wall

2. **Analyzing Each Option:**
- **(a) Heterotrophic nutrition:**
- Bacteria can be heterotrophic, meaning they obtain their food from other organisms. However, plants are primarily autotrophic, meaning they produce their own food through photosynthesis. Thus, this option does not represent a shared characteristic.

- **(b) Prokaryotic organization:**
- Bacteria are prokaryotic organisms, which means they lack a defined nucleus and membrane-bound organelles. In contrast, plants are eukaryotic organisms, which have a defined nucleus. Therefore, this option is not correct.

- **(c) Presence of flagella:**
- Some bacteria have flagella, which are used for movement. However, plants do not have flagella. Therefore, this option does not represent a shared characteristic.

- **(d) Rigid cell wall:**
- Both bacteria and plants have a rigid cell wall. In bacteria, the cell wall is primarily made of peptidoglycan, while in plants, it is made of cellulose, pectin, and lignin. Despite the difference in composition, the presence of a rigid cell wall is a common characteristic.

3. **Conclusion:**
- The correct answer is **(d) Rigid cell wall**, as it is the only characteristic that is shared between bacteria and plants.
